hello to everybody


i need help if anybody can add a parameter in the following bot.

The parameter will be regarding the spreads.

it will not opening new orders when the spread is bigger from the specific value.

 

 

 

using System;
using cAlgo.API;

Hi there,

You can add a parameter called MaxSpread and then write the following condition wherever you want

            if(Symbol.Spread <  MaxSpread)
            {
               // Do something
            }
