Screening price action vs S/R drawn using BB

Hi guys I’d like to make an automatic screening of something I’m usually doing manually but the process is rather complicated and I don’t even know if it’s codable…

Here below are the conditions to define the Support/Resistance lines (see attachment)

Step 1: Boll%b crosses 50 (or price closes below 20SMA)

Step 2 Boll%b crosses below 0 (or price closes below Bollinger (20 2))

Step 3 Boll%b crosses above 0.25 (or price closes above Bollinger (20 1)) => Define the close as “1DR” (one day red)

Step 4: Look back and check which candles are crossing 1DR
=> Define the highest of these candles as 1DLB (one day light blue)
=> Define the lowest of these candles as 1DW (one day white)

=> Look back condition: to define 1DW & 1DLB: Look back up to the last time price closed above Upper BB (20 2)

Screener:

Now that we have set the support/resistance levels (1DR, 1DLB & 1DW), I want to be able to screen a condition where the price is interacting with these levels in the future (I think the max lookback is 400 periods but the lookback period could be set as variable if you don’t wanna lookback that far)

For example after these levels are set, the price breaks out above 1DLB and then retests 1DLB after 20 periods. I wanna screen that condition.

Do you think this is “codable”?

Thanks in advance for your feedback and help.

Franck.
