I want a custom indicator turned to an E.A

I'm looking for a programmer to convert my custom indicator to an E.A. here are the instructions. The indicator generates signals using arrows if the indicator prints a green arrow that's a buy signal and if the indicator prints a red arrow that's a sell signal.............1. Opening and closing of orders: once the indicator prints a green arrow I want the E.A to buy at market price and if the indicator prints a red arrow I want the E.A to sell at market price instantly.The closing of orders happens if an opposite signal is generated I.e if  the indicator had generated a buy signal then after 3 minutes or 7 hours the indicator generates a sell order the E.A should close the buy order before opening  the new sell order so basically the E.A closes an order if the indicator generates an opposite signal.......Risk management: if the indicator had generated a buy order by generating a green arrow then after 2 minutes or 5 hours the arrow disappears from the chat (repainting) the E.A should close the buy order instantly once the arrow disappears and open a sell order which will only be closed if the E.A gets another buy signal( the E.A should also be tracking the signal that opened the order) this should be for both sell and buy orders. The programmer will insert an input where I will put the maximum drawdown in dollars which once is reached the E.A should stop trading.
