For sure we are not trading with whole balance but this is the trades profits for eth. It depends on the user and what token he likes. I think it is clear that the profit belongs to each coin and this is what displayed in the app
The sum profit that you mentioned belongs to eth only
What I'm saying is that the only important factor while evaluating trades is the R.
So, if you open a BTC long at 100k, targeting 110k, the percentage of the profit will show as 10%.
Here we come to the fun part of why percentage-based gains are a skewed method for any analysis.
Imagine 2 trades with 2% of your capital on each trade.
One is a trade targeting 110k,but with SL set at 98k. That's a 5R trade, equaling in actual 10% portfolio gain.
The other is with the same 110k target, but with SL set at 80k. Although the profit on the trade was 10%, it is a 0.5R trade, equaling 1% of your actual portfolio gain.
Theoretically, with 5 winning trades of 5% gain and with 1 trade at 3% loss you can be in the red - and your percentages would look like you're Jesus reincarnated.
