An Expert Advisor based on RSI Needed

Need an RSI Entry and Exit Robot Trades

1. RSI  P= 21, Overbought = 50, Undersold = 50

2. Entry should happen when after the RSI line touches middle line

      a. Enter at the close of candle  (Green Candle) after it goes above of middle line of RSI - for Long Trade

      b. Enter at the close of candle  (Red Candle)  after it goes below of  middle line of RSI - for Short Trade

3. Stop loss, Limit for both the trades: should be editable values (SL: 30, Limit: 40 default values)

4. If entry happens on the long trade at the touch of RSI line above middle line - it should exit when same RSI line touches middle line and closes below middle. (or by stop loss/limit - whichever is earlier).

Trade should automatically start in the loop each time RSI hits the middle line and closes above for long trade, closes below for short trade.

we can have robot for Long Trade and Short Trade separately (Two Robots?)

attached the screenshot - to show what I meant - however if more clarity is needed pls let me know.

Thanks
