Change the VPS Remote Desktop (RDP) port

It’s can be recommended to change windows remote desktop default port for added security or to change the entry port on your server to avoid a routing issue. You can change the default port with a few easy steps. First, you’ll define this port in a firewall rule, then you will change the RDP port.

You can choose to use any port that is not in use or reserved, there is a wiki list of all the ports that are officially or unofficially used. So it’s best to choose something that is not on that list. If you wish, contact our support team for a recommendation.

This process is considered an ‘advanced’ process as you need to modify the registry. If you fail to perform both actions correctly you will be locked out of your VPS and the only option is to completely reimage the server.

Therefore, we suggest you back up all important information before you attempt this. If you take care however you shouldn’t have a problem updating your port number.

Here are step by step instructions on how to modify your RDP port.

Step 1 – Change the Firewall to allow your new port

First you need to find the firewall. The best way to do this is to click on Windows icon and type in ‘Firewall’. You will see ‘Windows Firewall with Advanced Security’ appear.

  1. Open Firewall (Windows Defender Firewall with Advanced Security)
  2. From the left sidebar click on Inbound Rules
  3. From the right sidebar click on New Rule
  4. Select Port and click Next
  5. Select TCP and type the port number in Specific local port and click Next until you reach the step where you asked to enter a rule name, give the rule a name and Click Finish. (Repeat from #7 to #11 for UDP)

Step 2 – Change RDP TCP port on Windows Server

  1. Open registry editor app by searching for regedit in windows search or use RUN.
  2. Locate the following from regedit app:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
  3. look for PortNumber and right-click on it and Modify
  4. Make sure to select Decimal under Base option
  5. Change the port number in the ‘value data’ area to any number you prefer, let’s say 1234 and click OK
  6. Quit the registry editor

Step 3 – Restart the server to make the changes

  1. Double-check that you have entered the correct details for the firewall and that this matches the details in the registry.
  2. When you are sure you have completed all the above steps. Restart the server.
  3. Try to connect to RDP as usual but when you type the IP address, don’t forget to type the custom port number after the IP in this format IP:Port (e.g. 192.168.1.5:1234)
  4. You should now be able to connect through that specific port to your server.
  5. Bobs your uncle!

Know your predicted profit after a Goal

Succesful Betfair football trading

If you are a Betfair football trader wouldn’t it be great to know what your profit or loss would look like after the next goal? Whatever your Betfair trading strategy, it would obviously help.

This is important as, to trade successfully, you need to ‘frame’ your trade around a specific opportunity and fully understand the pay off. Knowing that one piece of information can help you decide how to manage your trade, know if it’s worthwhile and also where to pitch your exit trade/s at.

With Bet Angel you have the Betfair trading software and options to do exactly that. You can easily display your predicted profit or loss following a goal on your ladder or one-click screen. This profit/loss is shown in real-time and dynamically adjusts and updates as the time of the match progresses as the time decays, allowing you to adapt your strategy as the match progresses based on what’s happening in it.

Scenario – (Laying the Draw and show the Predicted Profit after a Goal)

For this example, I’ll use one of the most popular Betfair football trading strategies, lay the draw. In the image below I’ve already layed the draw pre-KO and can see straight away if the home team scores the opening goal I’ll make around £21.28, if the away team score first I’ll make a little bit more at around £30.19.

As the match gets underway and the time begins to decay the impact of a goal will continually effect the price the draw odds will reform at, as this changes so will your potential profit and this is continually updated for you in real time by the software so you can always be adjusting any exit/greening position accordingly while also being able to evaluate your risk/reward at all times during the match.

By contrast if you were to lay the draw in a match with a strong favourite, you will know you’ll have a good profit if the fav scored but if the under dog scores first this will cause the draw odds to shorten and put you in a losing position. In the image below you can see after laying the draw with a £10 stake, if the home team (the fav) scores first the predicted profit is £6.00, where as if the away team (under dog) scores first the predicted loss is -£10.39.

If you want to look at where the odds will at any point during the match but in the pre match period. It’s worth checking out Soccer Mystic which will give you this information.

How this is Done

To do this involves the use of the ‘+1 Markets’ from the fixture, as detailed in this similar blog which shows how you can displays the predicted odds after a goal on your Ladder or One-Click trading screens.

This works on most football matches where the appropiate markets are available on the betting exchanges. Whether you have a betting strategy or a trading one, it should help in the long term.

Just to give a brief re-cap of whats in that blog, by using the +1 markets these are effectively handicap markets which will show were the prices will reform around if either team were to score 1 more goal, then using Stored Values in Bet Angels advanced automation we can use those odds and look up the corresponding profit (or loss) against that price – and that’s what gets displayed to you.

Going back to the image at the top of this blog showing we’ll make £21.28 if the home team scores and, around £30.19 if the away team scores first if you were to scroll up to those values in the trade profit column on the ladder you’ll see the corresponding odds they relate to therefore you’d place your exit/greening bet around 4.7 if it looked more likely the home team will score first and around 5.4 if it looks like being the away team that will score first.

Displaying the Predicted Profit/Loss on your Ladder

Just as in that previous example all the files needed to display the predicted profits above your ladders have already been created for you to download and import into your Bet Angel. In total there are four files required which can all be downloaded from the following post on the Bet Angel forum

Once you have downloaded the files you would use them as follows.

Display Predicted Profit after a Goal.bls – this is a ladder settings file and needs to be imported into your ladder settings area, this will then display the ladder exactly as you see in the image above (you can of course use the Bet Angel ladder settings editor and edit any part of your ladder layout).


Profit Predictor after a Goal (Home).baf – this is a basic rules file and needs to be applied to the home team +1 markets in Guardian
Profit Predictor after a Goal (Away).baf – identical to the above rule but needs to be applied to the away team +1 markets in Guardian
Display Predicted Profit after a Goal (Match Odds).baf – this final rules file needs to be applied to the match odds market.

In the screenshot below you can see I’ve added the match odds market, the home team +1 and away team +1 for three fixtures and applied the relevant ‘Profit Predictor after Goal’ to the +1 markets and Display Predicted Profit after a Goal to the match odds market.

For example, the first fixture is Schalke 04 Vs Leverkusen
So, the Goal Odds Predictor (A) file is applied to Leverkusen +1 market (because Leverkusen are the away team)
And the Goal Odds Predictor (H) file is applied to Schalke 04 +1 market (because Schalke 04 are the home team)

And that’s all there is to it, when you open the match odds market of that fixture and place a bet on the draw (it can be a back or lay bet) it will continually update to display your predicted P/L should a goal be scored. You can place additional bets at anytime to add to or reduce your position and the predicted P/L will continually update

NB,To provide more accurate results I’ve included a condition that there must be greater that £1000 matched on the +1 market, so if you don’t see any values on your ladder then it will be because this condition has not yet been satisfied.

Trading the Home/Away Teams

With the rules file above you are not just limited to trading on the draw, you can use the same rules files to view your predicted profits (and losses) no matter whether your trading the home team, away team or the draw, all you need to do is make a simple change to the selection each rule is applied to.

This is done on the general tab of each of the rules in Guardian, so if you wanted to see your P/L from trading the home team you’d change the ‘Applies to selection’ 1 on the three rules files.

Betfair API – Greening / Hedging / Cash out issues

On Friday 19th June, without any prior notification, Betfair introduced some changes and new rules to their API. This had the effect of preventing ALL API software users correctly hedging position on the Betfair betting exchange.

Typically this would have exhibited itself when trying to implement greening. The Betfair exchange wasn’t accepting orders correctly, leaving stray orders in your unmatched bet area. This meant that customers were left with slightly uneven positions in the market which they were trading.

Changes to the API should be announced in advance and that gives us time to implement and test any key changes. On this occasion Betfair changed the API without informing us, so the first we knew about it was when we spotted it ourselves when trying to hedging our own trading postions. Betfair didn’t acknoledge any changes until much later than evening.

Why did this happen?

Betfair felt the integrity of the exchange was threatened by an exploit that existed.

There has been a loophole in the way Betfair round bets for many years and is often exploited by a few users so it’s is something that’s been on their radar for quite some time, obviously though something must of happened during last week to prompt them into doing the sudden unannounced change when they did on Friday.

For example – a 13p @ 1.06 back bet is ‘unfair’ as it ‘ought’ to win 0.78p, but actually – due to the old rounding – wins 1p, which is a 28% uplift in profit.

However having hundreds and thousands of tiny bets like that hitting the exchange from various accounts purposely exploiting this loophole is bad for API stability which effects us all so its not a bad thing Betfair have taken decision to close this exploit once and for all.

What we did

Although no one was aware of this change coming, we spotted something was wrong within hours and moved quickly to release an updated build of Bet Angel later that same evening to our forum to try and reduce the wider impact these new changes were having on customers using stakes below the £2 Betfair minimum, particularly when greening up with small stakes. This enabled Bet Angel users to continue using the software and their trading throughout that weekend.

Once we were able to speak with Betfair and get clear confirmation of what exactly what it was they changed and what the new parameters and calculations now being used were we could then issue another build of this Bet Angel at the start of this week with tighter coding.

Updating Bet Angel

We recommend updating Bet Angel. These updated versions will still allow you to continue to place bets and green up with small stakes still. But due to the new Betfair rounding rules, there may be times when your P/L still ends up uneven by a few pence. So we have also updated the Bet Angel logging to spot when the API rejects these bets due to rounding, this allows users to see clearly if that was indeed the reason their order was rejected or not.

If that does happen you will see an error written to your Bet Angel log which looks like ” While Greening Up Unable to Place Lay Bet Due to Befair’s Rules Regarding Payout/Liability Rounding”

The latest builds of Bet Angel are now;

Bet Angel Profesional V1.52c

Bet Angel Trader V1.4.4c

These can be downloaded from both our forum and main website, once installed you will see one of those build numbers in the bottom right corner of the blue login window or by clicking the ‘about’ tab once logged in.

If you are installing the latest version of Bet Angel to a VPS you may need to follow the specific instructions listed on this blog post.

Note; If you are not using the latest version, you will also see a pop-up message at login prompting you to download and install the latest version.

For full details of the changes made by Betfair on 19th June please see this post from their developer’s forum

Installing software on your VPS

You may want to, or be required to, install software or updates to the software you have installed on your VPS. If you can’t install software on your VPS it may be that the download is “blocked”.

Because your Windows server / VPS is connected to the internet 24×7, security tends to heavily restrict what software can be installed without your specific permission.

So there are two ways to ensure you are able to install or update your software.

(1) Copy and paste from your local PC to the VPS

Ensure the clipboard is enabled in your client software, ‘client software’ is the software you use on your local computer to connect to the VPS. You should find the clipboard under an options or settings menu if you wish to check.

Download the software you want to install to your local PC. Then copy and paste it to the VPS. You should find that the software is ready to install.

(2) Unblock the software downloaded onto your VPS

If you download the software using a browser directly onto your VPS then you may need to unblock the software.

To unblock the software, download it to the VPS and make a note of where that file is located.

Then right-click on the icon and locate the ‘Unblock’ option on the bottom right of the dialogue box. Click to unblock the software and you should be able to run the application.

Changing a password on a Windows server / VPS

Chaning the password on your Windows server

When you first receive your Windows VPS you will be given a default password. For security reasons, we suggest you immediately change your password to something new.

To do that, go through the following steps: –

Click on the Windows icon in the bottom left hand corner of your screen when you are logged into your server. Then locate the ‘Windows administrative tools’ and click on that function.

This will bring up a new window with a range of options available to you. You are intereted in locating and managing a user profile, so click on the computer management function in this list.

In turn, this will active another list of options and you are interested in locating and clicking on the ‘Local Users and Groups’. This will allow you to locate all the users that have access to your VPS.

Click on the ‘Local Users and Groups’ will display another list and you need to click on ‘Users’ on this list. This will then display to the right a list in the dialog box.

You will see the adminstrator account in this list and to change the password, simply right click on the ‘Administrator’ username to change the password. You can then close down all the open menus and return to using your Windows server / VPS.

Important notice

If you change the Administrator password and then forget it, there is no way to access your Windows server. You will need to apply to your provider to either do a password reset at the datacentre or re-image the server. So please make sure you make a note of the password.

Default administrator access on your server gives you, or somebody else with your password, full access to all your server functions. So treat this password with great care.
