Calculate the number of coins for a deal with a fixed amount of risk

[iarkusha]

Can someone tell me, it's very important to calculate the number of coins for a deal with a fixed amount of risk (including commission).

For example, at a risk of $ 100

100 $ / (buy level - stop level)) = number of coins

How to resolve the issue with the Exchange Commission 0.25% at the opening and closing? For example Bittrex has 0.25% commission for all deals.

How to calculate the correct number of coins so that in the end the total loss was only $100 ?

I think it should be like this,

Bittrex will take the %0.25 of bought and sold coins.

If you want to buy X amount of coin you will receive 99.75% * X amount.

And when you want to sell you will get the value of 99.500625% X as Bittrex will cut the 0.25% of 99.75% * X amount.

Rearrange the equation as follows:  100$ = (buy level - stop level) * X

And then lets put the calculated percentage values to the equation:

100$ = buy_level * 99.75X - stop_level * 99.500625X

I think this should do the trick.
