Support and Resistance mql5 EA for multiple currency pairs - very simple logic

Very Risk Robot but very simple logic

When applied to a chart, EA will draw Support and Resistence on chart based on multiple touches/recent highs and lows
When not applied to chart - EA will monitor Pairs listed in input for entry signals listed below

EA will be run on 1hr and 4hr Timeframe 

When Support is rejected by a Bull Candle on any of the pairs, at close of candle EA will place a Buy

SL below the Support level / recent low (or lowest point in last x amount of bars)
TP at input level
When Support is broken through by a bear candle by most of its body, this Support becomes resistance and we wait for a Bear candle to reject zone

When Resistance is rejected by a Bear Candle on any of the pairs, at close of candle EA will place a Sell
SL above the Resistance level / recent high (or highest point in last x amount of bars)
TP is at input level
When Resistance is broken through by a bull candle by most of its body, this Resistance becomes Support and we wait for a Bull candle to reject this zone

Only allow 1 trade to occur at a time due to Margin and risky trading
If price rejects level and EA already in a trade, ignore entry signal
If 2 or more pairs show rejection at same time - choose pair with largest top wick for Sell or bottom wick for buy
