Develop Expert Advisor in MQL4 or MQL5 EA

-----SCHEMA:------ 1 -Check if there are trade open 2- Fixed levels of Martingale 3-Open trade according to the scheme of the martingale 4-Close the trade if the total profit (of all trades: revenues -Loss) is greater than zero 5-Close all trade if you reach a number of lots equal to X I have the complete algorithm step by step. It just needs to be translated into the MQL language -----The trading system----- VARIABLE MODIFIABLE Profit closure pip = 5 Trailing_stop = 10 pip Delta = 20 pip Martingale multiplier = 1.4 Max_order_limit = 0.4 lots Once there is an open trade, the trading system places a pending order opposite (at a distance from the first trade equal to the variable delta). This opposite pending order have a number of lots larger than the first trade (equal to (lots first trade) * multiplier maritinagala). If no trade hedging is open, and if the position is in profit then activate the trailing stop. Otherwise activates a system similar to recovery area. When the number of open lots arrives to a certain amount (equal to Max_order_limit) closes all positions. Otherwise close positions once it is reached a profit (total of all trade open) which is equal to the variable profit closure (5pip).
