The logic of te ea begin with an if statement for buying or selling then for example if a x lots buy order is executed place a sellstop order at a certain distance with 2*x+1*(initial lots).

If the sell order is executed place a buystop order with 2*lastlots+1*initial lots at the same price of the first buy order.

If the second buy order is executed place a sellstop order at the price of the first sell order with

2*lastlot+1*initial lot,.... and so on.

And i want to be able to control numbers of orders for example if i want only 2 orders then stop when the total orders equal to 2.

the take profit should be equal to the intial distance and the stop loss equal to 2*initial distance.

When the takeprofit or the stoploss is touched close all orders.
