A two-way system to prevent large positions

A trade above the threshold lot size, with the same reverse position. The purpose is to restrain yourself from trading high lots.

In the configuration section, we would like to be able to choose between a default threshold and a currency and threshold.

Example.( Default:2.0 and XAUUSD;1.0  GBPUSD;0.8)

If there is such a thing in the first place, you can tell me and I will pay the price.
