Control amount of pending orders triggered at a tim e (QUEUE)

Hello all,

I would like a program created that allows me to control the amount of pending orders placed by me, that will be triggered at a given time.

For example: lets say I see 4 possible trade setups with 4 different currencies pairs. I place 4 pending orders. Meanwhile I have enough margin to comfortably cover 2 /4 open trades. I want to be able to set a control on the

pending orders for this example that the first 2 pending orders get triggered meanwhile the other orders are on hold (QUEUE)  till the open orders are completed either by take profit of stop loss. Once one of the orders is

completed, the other two orders have a possible opening to be triggered whichever ones first.

Please advise

Andre
