I have an ea in MetaTrader that automatically configures the position size based on the percentage of risk and the Stop loss, and I have this configuration in different charts open at the same time with an expert in each of them so that when the signal appears I click faster. I also plan to buy a normal keyboard and reconfigure it so that each key has a macro. Does anyone know how I could do this so that when pressing a specific key this expert's buy key is activated on a certain chart? For example, a keyboard key opens a sell position on the euro dollar chart by pressing the sell ea button of eurusd chart.
