Create a mt5 Grid bot EA

Set configurable parameters - lot size, grid size & close percentage, increment value.

When there is no open trade, open a buy and sell at the same time and same price, with lot size as defined in the lot size variable. 

Set pending orders - buy and sell at previous lot size + increment value; price at current trade price + grid size. 

buy and sell at previous lot size + increment value; price at current trade price - grid size. 

Keep repeating this upto 15 levels. 

After open the trade either buy or sell is closed if it is in profit and reaches the next grid level.

And the other trade in loss is closed when the price comes back to the close percentage of the total increase distance from the start of the trade.

After prices goes till 20 - 4 buys are closed in profit ( at 0,5,10&15) now open trades are Sell ( at 0,5,10,15,20) & buy at 20. 

Close % is 70% so the total distance of increase is 20-0=20. And 70% of 20 is 14.4

Now when prices reaches 14.4 we close all the open trade.
