Trademate Sports Betting Results April 2021

To give you a bit more insight into the performance of our users and software, every month we go through our overall results, as well as taking a deeper look into our performance with each individual sport and leagues.

We are doing this with the help of our back-logged data. This is because the big data tool inside the software has a cap of 10,000 trades to speed up loading time, so for some of our sports it will not show results of every trade placed in February. There are no filters on this data, it is every trade placed no matter what the odds range, time placed, edge, etc.


Before we get into how we performed in April, it’s important to note some of the limitations of the data we will show you:

  1. For the Flat ROI calculations, stake sizing of €1 per trade is used to remove the effect of users with large bankrolls skewing the results. Also, this way we can see whether our edge is based on beating the market, rather than the Kelly Criterion.
  2. There is a chance that some of the bets in this data are duplicated as multiple customers could be placing the same bet. But the chances of this happening regularly are low as our user-base is quite geographically diverse, which means they have to use different bookmakers.
  3. Something else that is possible but even more rare is customers logging their own bets manually within our software. Those bets are not recommended by us, but they will still appear in this data, win, lose or void.
  4. Some of the sample sizes will be very low, meaning no conclusions should be taken from those data-sets. The bigger the sample size the more accurate the data. Generally, a sample size of under 2,000 trades will include a lot more randomness and needs to be taken with a grain of salt or completely ignored

Results & Key Findings

In the month of April 167,239 trades were placed, €9,980,915 was turned over and €361,309 was profited and a whopping ROI of 3.62%! Here is how each sport performed, broken down into recommended leagues (popular leagues) and non-recommended leagues (lower leagues):

A great month all round for Soccer traders! After a bounce back last month for recommended leagues, we see them perform strongly again returning a 4.18% ROI. It seems midweek games are flowing in fast as teams and leagues try and catch up with the missed games due to the pandemic. Non-recommended leagues which never let us down, certainly haven’t disappointed this month. They return a healthy 5.12% ROI as well.


Back to back incredible months for Tennis. Over a sample of over 11k trades we see huge returns with an ROI of 10.43%. That makes it the standout performer for two months running! Hopefully people continue to get the most out of Tennis on Trademate as more and more competitions begin as summer is slowly upon us.


NBA and Euroleague saw another loss this month with a minor -0.83% ROI. Usually two very consistent leagues, I’ve noticed a large increase in injury lists among NBA teams. A lot of players have been out due to vaccine jabs and it also doesn’t help they are playing around 4 games a week at the moment. Maybe it’s just a matter of turning down the time frame and betting closer to tip off until the season catches up to the players, however it could just be variance catching up as prior to march NBA and Euroleague were very consistent for us. Non-recommended leagues were profitable as usual, still a large gap between edge at placing and closing however it still doesn’t prevent a positive ROI of 3.14%.


It wasn’t a warm welcome return for MLB, safe to say it was a strikeout as the worst performer of all sports with bigger sample sizes. Hopefully this can turn around quickly going into May as the season starts to settle. If traders are struggling with understanding betting on Baseball as they do not follow the MLB personally, we recently covered it on YouTube a couple weeks ago so check that out. As for non-recommended baseball leagues they turned over a profit this month, but with a small sample size again.

Ice Hockey

NHL has been up and down for us this year but April has been a solid month with a very nice ROI of 3.52%. Non-recommended leagues didn’t slack off either coming in with a 4.25% ROI. Good to see a much better swing in our favour for Hockey traders, hopefully January and March were just bad variance and there’s a lot more month’s like this to come for Ice Hockey.

CS:GO (Esports)

CS:GO continues to impress, never a huge sample size but that doesn’t seem to ever change the results. Bookies are clearly weak with their pricing in these markets, I expect they know so be cautious to prevent account limitations. Another 5.09% ROI this month speaks for itself on how profitable CS:GO betting can be.

DOTA 2 (Esports)

A real down swing for DOTA bettors in April seeing -7.19% ROI, again a small sample size but it’s not what we like to see. I notice a fair drop between edge at placing and closing, however 3.33% average closing edge isn’t bad and I expect a large amount of that negative ROI is just poor variance over a small sample. We will have look into how best to maximise profits in DOTA markets!

Rugby League & Union

Again, very little sample size to deliver conclusive overviews of Rugby trades, as 2021 continues we’ll have more data over multiple months to get that in-depth analysis.


And that’s all she wrote for my latest Trademate Sports monthly results. Although most of these results come with huge samples, it’s important to take them with a grain of salt. Just because a sport is profitable or unprofitable doesn’t mean that you trade on every single bet that comes through our software. Follow our recommended presets, and run some simulations on our big data tool yourself to figure out the best odds ranges, times to trade, etc.
