New comment
 

  

Hi anyone help me on this , i'm trying to develop a EA using python language and i need to calculate the lot sizes to fix my risk reward ration .

attaching a images , in this image you can see 3 different brokers and when we trade 0.01 lot thee of them are giving different profits .

i need to know how we can implement the calculation in your Trade manager i have used the lot size calculation that was working perfectly in these brokers

if possible please share the calculation method , like what are the parameters using to calculate the profits like your trade manager


i need to risk 50$ on a single trade : in FXTM just need to open a trade with 0.01 lot and 50 point sl it will be 50$ risk

in 8cap 0.10 lot for 50 point sl

mff its 1 standard lot for 50 point sl

i need this to calculate from python code

from python i can get the following information from symbol properties :

Please read the following post ... Calculation of lot size

It is not specific for Python, but the basics are the same, and the Python API offers similar functionality.
