I need an EA for MT4 based on supertrend indicator and supertrend line

I am looking for a supertrend EA. There is a  supertrend EA online similar to the one i want however it doesnt work properly. the ea is by quivofx supertrend basic ea     (feel free to google this ea to get idea of what i want)  what i like about this ea is there is option for the the supertrend line to be the stop loss for the trade .

However the big problem with this ea is that sometimes it opens order with the stop loss and sometimes it doesnt. it is not consistent. 

I need the EA to:

1)execute the trade when the candle closes above the supertrend or below the supertrend line,

2) the stop loss value has to be the supertrend value ( IN PICTURE BELOW WHERE DOTTED LINE TOUCHES NORMAL LINE), The lowest point or highest point of supertrend line ( if that makes sense) basically the stop loss  is the supertrend value for that candle that closes.

3) If i could get risk management option on this ea that would be great, example it calulcates the lot size depending on the stop loss

4) It must work properly on lower timeframes as i use 5M CHARTS. it must work consistently

Below is example of what i wantL
