Double Lot Size After X% Gain [closed]

I need help if someone can please add the formulas to the cells so that the lot size will double by the % entered after a entered % profit gain is reached. The profit is based on lot size X points value. For example someone starts with $20 account with 001 lots and they enter double lot size at 400% so when the running balance reaches $80 it will double the lot size to 0.02 and therefore increase the daily gain to double. Here's the editable link to the spreadsheet please see the "Forex Points" tab:https://docs.google.com/spreadsheets/d/1uvt9efqMC_XZvxCw3h7zqISxm-S3MhVNY0OBv3QReKI/edit?usp=sharing
