can someone help me code this indicator for price action

hello every body

i have an ideas about price action that need to be tested so i want this 2 indicator please


i want an indicator with 1 parameter let's name it ( number of candles )

let's say i make this parameter ( 3 ) so the indicator will give me an up arrow at the first green candle that close after (3 ) constitutive red candles

an give a down arrow at the first red candle that close after ( 3 ) constitutive green candles

as attached picture : the highlighted candles is the candles that meet the rules either up or down

and let's say i change the parameter to 5

the following candles only will be highlighted

Perhaps this will help

thank you very much i will try it and till you
