Add RiskManagement feature to my molanis EA

Hi,

Ive created a EA with molanis, which is working fine. The entering of the trades will be made by the bollinger indicator.

I need an additional feature for RiskManagement.

The lotsize should be calculated via the stoploss and free margin.

for example:

if we have a free margin of $1000.

the SL of the next trade is 50 pips.

my maxRisk is 2% 

trades lotsize = free margin x 2% / 50 pips x $10

or in other words: my max risk in $ / my SL value in $ - $20 / $500 = 0.04  is the lotsize, that will be traded.

attached you will find the molanis EA for which the extension should be coded, a spreadsheet in which you can see how the lotsize will be calculated and my MT4 backtesting journal.

for a better communication english should be spoken fluently.

Thanks for you attention, Tom.
