If you're looking to optimize your trading strategy, the EXP_MAX_LOT is a game changer for MetaTrader 5. This Expert Advisor (EA) calculates the maximum lot size you can use to open a position, leveraging the entire free margin available in your account. By default, the calculated lot size is displayed in the upper right corner of your chart, making it easy to see at a glance.
Originally developed in MQL4, this EA was first shared on mql4.com back on June 21, 2012. It's been a reliable tool for traders ever since!
