I need to create an Expert Advisor trading robot using existing indicator "target-bands-indicator.mq4"

The EA will have 2 different modes to choose from:
	Buy only
	Sell only

Each mode will have 2 functions to perform. When using "Buy only" mode, if a bar closes bearish and is also under the bottom band the EA will open a market order to buy. 
The 2nd function of "Buy only" mode will close all orders on chart if price touches the top band

When using "Sell only" mode, if a bar closes bullish and is also above the top band the EA will open a market order to sell.
The 2nd function of "Sell only" mode will close all orders on chart if price touches the bottom band

I will have orders open on multiple different chart assets so the EA must only close orders for the chart asset the EA is attached to

The EA will close orders immediately upon price touching the top/bottom line of "target-bands-indicator.mq4" depending on its mode. 
Do not wait until bar close to execute EA for closing orders

Adjustable inputs required: 
	EA Mode (2 options) = Buy only, Sell only
	Halflength = 55
	BandsDeviations = 0.618
	Lot Size = 1
