Determines the usual volatility (median of the True Range on 3 bars)
Norma = Summation3 - Highest3 - Lowest3 You can also look at the full picture above.

Can you help me develop this string on FX.
Thank you

I am trying to recreate the condition of oversold and volatility by following this guide.

REM Filtriamo i valori il cui RSI é in ipervendita e in inversione.
// Criterio di filtro : RSI < 30 e crescente

Filtro = RSI < 30 AND Momentum1 > 0
REM Determina la forza della tendenza a ribasso
REM Trova il punto più alto sulle 20 barre precedenti.

Massimo = Highest20
REM Determina il declino a partire dal punto

Declino = Massimo - Close
REM Determina la volatilità abituale (mediana del True Range su 3 barre)

Norma = Summation3 - Highest3 - Lowest3Velocita = Declino / Norma
REM Mostra risultati

Print[Filtro](Velocita AS"Forza a ribasso")

I don't understand what you mean by Massimo = Highest20 what do you mean by (High) after Highest [20].

same for Filter and Norma, the confusion between ()

I inserted my mql4 if you can give it an eye and tell me where I went wrong please.
