Trademate Sports Betting Results May 2021

Written by Miles Wigby.

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 March. 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 March, 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 May, 134,241 trades were placed, €8,005,423 was turned over and €173,259.39 was profited at an ROI of 2.16%. Here is how each sport performed, broken down into recommended leagues (popular/bigger leagues) and non-recommended leagues (lower/smaller leagues):

Another month with tons of Soccer trades and steady profit all round. With the regular season coming to an end and the Euros around the corner we expect a smaller sample size in the upcoming months but hopefully nothing changes in the profit department. Recommended leagues have another profitable month at 2.1% ROI to end the season. Non-recommended leagues see just a 2.57% ROI which is very good, however, lower than the few months. Especially considering the consistent 4% + closing edge Trademate gets in those leagues. As always on Trademate, soccer traders saw some good profits in May.


After two incredible months in a row with tennis betting on trademate, May saw some variance to the downside. Both recommended and non recommended leagues had a negative roi. Some variance has to be expected with how well tennis has performed in recent months. Hopefully as we go into the summer and more major events come around, Tennis gets back to its usual profitable ways!


After two poor months in a row for the NBA and Euroleagues they take a turn for the good just as the playoffs start! Hopefully some found our recent NBA playoff preview article helpful which can be found here. Here we spoke about injuries affecting the NBA and shorter time frames should help the results. Non-recommended leagues were also profitable as usual returning a 1.77% ROI in May.


May was not a good month for MLB traders, despite achieving a good closing edge it returned a negative -3.82% ROI. As the season carries on, we should see variance swing our way. As for non-recommended Baseball leagues, they had another profitable month with a good 3.33% ROI, so that’s a conciliation for Baseball traders.

Ice Hockey

I thought last month was incredible for ice Hockey traders but this month got even better! It’s safe to say Ice Hockey was the standout performer this month. NHL trades saw an ROI of 9.63%. Non-recommended leagues returned an ROI of 11.17%. Those results speak for themselves, hopefully Ice Hockey can keep up this amazing run of form over the last two months.

CS:GO (Esports)

Consistency is important in sports betting and if you’ve been following Trademate’s results for a while you’ll have seen how consistent CS:GO trading can be. Never an overwhelming same size but the ROI is nearly always profitable regardless. May returned nice 3.18% ROI for traders.

DOTA 2 (Esports)

Still a small sample size, however, a huge upswing for DOTA traders. In May DOTA returned a massive 9.67% ROI. A solid turnaround from the last two months. This just shows if you consistently take a positive edge, over a large sample size you’ll see good profits.

Rugby League & Union

Limited sample size as usual for both recommended and non-recommended leagues, especially Rugby League. Some mixed results, however generally profitable. Recommended leagues saw a small loss of -1.87%, whereas non-recommended leagues were profitable, returning 3.06% and 10.13% ROI’s retrospectively.


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.
