Bitmex calculators return eroneous calculations:
A position size with high leverage, without recognizing the fees impact! The loss will be severely superior to your expected trading risk! So, the risk reaward is completely wrong, you can easily lose more than win on every trade and liquidate your capital without understanding! It's sure Arthur agrees...
Calcmex return the maximal position size assuming the type of input and output expected. In the potential loss are included your trading loss (PnL) and your tradings fees (entry and exit, maker or taker)
Check this in the picture example:
Trading loss is 93,89$
Entry fees: -3.05$ (this is a maker entry) and Exit fees: 9.15$
So total fees are: 6.10$
the total loss is 93,89$+6,10$ = 99,99$ wich correspond really with the trading risk (1% of $10 000)
