Does anyone have the knowledge to create a small script for MT4 that will close 70% of your position rounded up - for both 4 digit and 5 digit brokers, Standard, mini or micro? 
I don’t know who you trade with but I just noticed with the newest update that IBFX included an EA that will partially close out orders so you can split a single order, any percentage you like, up to five times.
Awesome, I didn’t know that - However, I do not use IBFX so just looking for a small script to do it. Thanks!
