Modify an existing Indicator

Hi there!

I have an existing indicator and I would like to add SnR level inside it, the developer can create the SnR code by himself or he can use icustom to use the properties of an SnR indicator I’ll provide later. The existing indicator is an arrow indicator so I’d like to get signals when those conditions are met:

For CALL signal: Existing indicator gives a call arrow on bar 1, the wick (low) or Close of bar 1 must equal to the actual SnR level, Close of bar 1 must be lower than bar 2. Don’t take signal if the body of the candle break the SnR level.

For PUT signal: Existing indicator gives a put arrow on bar 1, the wick (high) or Close of bar 1 must equal to the actual SnR level, Close of bar 1 must be upper than bar 2. Don’t take signal if the body of the candle break the SnR level.
