Turn existing indicators into a trading EA

Hi, a trading robot is needed for my indicators. One indicator will give arrow signs and another indicator will provide take profit (TP) and stop loss (SL) position. This requirements are below.

• The EA will execute buy or sell orders under 1 min chart when arrow signal show under certain conditions. The time frame will be adjustable. The frequency of the arrow signals (Fast/ Slow) will be adjustable.
• The EA will have the option the adjust the lot size.
• When EA open buy position, TP is the upper channel boundary shown by another indicator. SL is either the lower channel boundary or when an reverse arrow sign is shown. The channel boundary is adjusting every 1 min so the TP or SL position should also be adjusting according to the channel boundary. The variables of the channel should be able to adjust. 
• When EA open sell position, TP is the low channel boundary. SL is either the upper channel boundary or when an reverse arrow sign is shown. The channel boundary is adjusting every 1 min so the TP or SL position should also be adjusting according to the channel boundary. The variables of the channel should be able to adjust. 
  
• The same channel indicator is used for buy or sell position.
• Once position is closed. The appearance of the same arrow signal will not trade until the next reversal signal is shown. 

Someone with a track record of programming in MQL4 and developing products for MT4 will be highly appreciated. I look forward to receiving feedback on the feasibility of this project.
