Help Strategy Grid Mathematics
I'm looking for help in creating an Expert Advisor
I have an idea to create a Grid strategy but I can't make it work.
If anyone can help me with the creation I would be really grateful.
EA open buy and sell positions on each line, must increase the value of the lot by a value on the previous lot, for example 1 line lot 1, second line lot 2, third line lot 3. this rule must be followed if the market is favorable on the previous line, if it is not favorable he must purchase the value of the base lot. you need to be able to set take profit, stop loss and traling, you must follow this rule for the buy when it goes up and for the sell when it goes down. can you help me?
