Check If True in a certain time frame | Pinescript V5

Question

My pine script code has the following problem

working version 1:
buy_signal = condition1

working version 2:
buy_signal = condition1

working version 3:
buy_signal = condition1 or condition2

but with the following it doesn't generate any trades...

The only one not working is:

buy_signal = condition1 and condition2

This must be due to the different release dates of the information, which means that they are not true at the same time.

That's why I need a function/ Workaround to check if a condition is true in a certain time frame

Answer 1

You can use ta.barssince() to see when your condition was true. Then use that as a condition.

ta.barssince()

Counts the number of bars since the last time the condition was true.

ta.barssince(condition) → series int

Something like this:

barssince_cond1 = ta.barssince(condition1)
barssince_cond2 = ta.barssince(condition2)

buy_signal = false

buy_signal := if (condition1 and condition2)  // If both conditions are true on the same bar, then buy
    true
else if (condition1)  // If only the condition1 is true, check when was the last time condition2 was true
    if (barssince_cond2 > 0) and (barssince_cond2 < 5)  // Was it true within the last 5 bars? Then buy
        true
else if (condition2)  // If only the condition2 is true, check when was the last time condition1 was true
    if (barssince_cond1 > 0) and (barssince_cond1 < 5)  // Was it true within the last 5 bars? Then buy
        true
