2% x $100,000 = $2000.
1 pip movement corresponds to 10 dollars if trading 1 standard lot. Maximum risk $2000 means that I can bear at most 200 pips loss.
Because my stop loss is set to be 35 pips, this means that I should trade no more than 200/35 = 5.71 standard lots per trade. Thus max standard lots per trade = 5.71. For safety reasons, I‘ll just trade 5 standard lots at a time.
