Trademate Sports Betting Results July 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 July. 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 July, 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 July, 120,689 trades were placed, €12,081,029 was turned over and €120,963.6 was profited at an ROI of 1%. Here is how each sport performed, broken down into recommended leagues (popular/bigger leagues) and non-recommended leagues (lower/smaller leagues):



Profitable month all round for Soccer traders. Sample size is bigger again and getting close to regular numbers as the season is starting up again. Noticeably, non-recommended leagues had it’s highest number of bets in 2021, probably as its midseason for some leagues outside of Europe, specifically Latin America. The 70k+ bets is 4 times higher than any other sport, of which most are in small breaks. It’s positive to see there’s no shortage of trades even in the summer break period for Europe. The Premier league and more are back next month so recommended leagues should follow suit soon enough, I’m sure all football fans are excited for the return.


Underwhelming results on the Tennis trades after last month's stormer! However, there is a much lower sample size on the recommended Tennis as Wimbledon ended at the start of the month. Novak Djokovic, as expected by many, won his 3rd Wimbledon in a row. There’s currently a small break before the next major tournament. August will feature the Western & Southern Open in Cincinnati in the build up for the start of The US Open in New York right at the end of the month. Hopefully Tennis trades will quickly get back on track and perform just as well as they did during Wimbledon.


With play-off Basketball finishing and the season ending for the NBA and Euroleague, the sample size for recommended Basketball has dropped off. Non-recommended leagues, however, have continued to perform strongly, returning a 2.43% ROI for traders. The NBA and Euroleague will have a 2 month off-season, expect to see some big transfers and trades which will have a huge impact on contenders for next year. It only takes 1 or 2 new signings to completely change a basketball team, Jrue Holiday to the Bucks last year is the best example, winning a ring in his first season. Keep an eye out, not only for big transfers but for ones that really suit the style of basketball and complete a team missing just a few pieces.

Ice Hockey

With the Ice Hockey season coming to a close the sample size dropped dramatically. Not much analysis to give here, with that sort of sample size results will be somewhat random. We look forward to welcoming the sport back in a couple months as it was generally very profitable throughout 2021.


With the MLB season in full swing we are now starting to see some very good results. July returned a whopping 8.3% ROI from MLB trades. It was a slow start to the season for MLB trades but now further into the season it’s been two great months in a row, hopefully traders have found the right parameters for MLB betting and the profits continue!

CS:GO (Esports)

CS:GO remains undefeated in 2021, seven profitable months consecutively. July returning just a 1.31% ROI is actually the worst performance for CS:GO so far. This just stands to prove how profitable the trades can be and the bookies really struggle to get accurate odds for these markets.


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.
