Convert my strategy to ea

hello,

i need to convert my strategy to ea

my strategy is:

each pair opens virtual buy and virtual sell with chosen lot size and if the pair reached to profit i choose it open real order whether it buy order or sell order depends on the virtual profit and at the same direction and put lot size, SL and TP  variable

for example:

EURUSD pair open virtual buy and virtual sell with lot size i choose for example 0.01 and i choose if it reached one of these two orders to for example profit of 2 USD for example lets say it is the virtual buy order made 2 USD as profit then opens real buy order as same direction of the virtual order

Thanks a lot
