Let´s start with the Classic Trade Mode and auto lot size calculation
The classic trade mode calculates for you the lot size automatically.

You get proper money management if you set a fixed percent risk for every trade. Metagrid calculates the lot size for the risk you want to take. Place a stop loss, click the trade button and Metagrid does the rest for you. It also works for pending orders of course.

Don´t care anymore about the right lot size!
