How to run a scan screener back in time, some days ago

Hi,

I’m trying to run a scan inspired by the Ichimoku Tenkan-Kijun Cross (screener) written by Doctrading.

But instead of matching “now” I would like the results to match a variable day in the past, (for example 7 days ago)…

What I’m basically trying to achieve is to have :
• Tenkan over the Kijun
• Tenkan & Kijun > Kumo
• Close > Kumo
• Chikou > Kumo

And this should match the 7th bar ago (not the current one..)

I was wondering, is that actually possible to run a scan back in time ?

Thank you for your help…

So far I came up with this.

// Original code
// Ichimoku Tenkan-Kijun Cross (screener)
// https://www.prorealcode.com/prorealtime-market-screeners/ichimoku-tenkan-kijun-cross-screener/

INDICATEUR = 0

period1 = 9
period2 = 26
period3 = 52

howManyDaysAgo = 7

period1 = period1 + howManyDaysAgo
period2 = period2 + howManyDaysAgo
period3 = period3 + howManyDaysAgo


Tenkansen = (highest[period1](Dclose(howManyDaysAgo)) + lowest[period1](Dclose(howManyDaysAgo))) / 2
Kijunsen = (highest[period2](Dclose(howManyDaysAgo)) + lowest[period2](Dclose(howManyDaysAgo))) / 2

SSpanA = (tenkansen[period2]+kijunsen[period2])/2
SSpanB = (highest[period3](high[period2])+lowest[period3](low[period2]))/2

Chikou = close[period2]

// ACHAT
C1 = close > SSpanA and close > SSpanB
C2 = Tenkansen > Kijunsen
C3 = Tenkansen > SSpanA and Tenkansen > SSpanB
C4 = Kijunsen > SSpanA and Kijunsen > SSpanB
C5 = Chikou > SSpanA[period2] and Chikou > SSpanB[period2]

IF C1 and C2 and C3 and C4 and C5 THEN
INDICATEUR = 1
ENDIF
