An Indicator that identifies an engulfing pattern

I am looking for someone to create an indicator that recognises the engulfing pattern.

However, I do have strict rules/requirements for a specific engulfing pattern.

These are the rules:

BULLISH ENGULFING

If the highest price ( Wick) of a red ( Bearish) candle is within the body ( i.e between the open and closing price) of the first bullish

candle that closes since the red candle closed, place a blue arrow on the red candle

- see attached Bullish engulfing v1 and v2

important - if a candle closes below the closes below the closing price of the red candle before the rule above is met, It is invalid and I dont want it to show

-- see attached bulish engulfing v3

The rules for a BEARISH ENGULFING is the exact opposite

if this is done well, I have 2 more orders that I want to place with the same developer.

Thanks
