Gap detection at the beggining of the day

[bourasrafik]

Hi,
I'm building my own strategy and I'd like to detect days with gap between closing market at 4PM and the the opening bell (9H30) and avoid entering position during the first hour, using the strategy builder, is there a simple way to be able to detect it at 9H30, i thought doing it by adding price condition at 9H30 and compare it the the one at 4pm the day before but the price have only var parameter and not the day/time.
Is there a simple way to detect these kind of gaps ?
Thanks

Hi bourasrafik, thanks for posting. There is an example here on making a time filter:

The idea here would be to only trade if the times land within the defined time filter.

Hi Chris, I'm able to filter by time and by date but I need to detect the jump between 4pM closing price and 9H30AM opening price and if greater than a predefined value I do not enter a trade for few hours, it's simple to do it by code by I'm looking to a way to do it in the builder to avoid to an endless coding cycles
It should work in both sides (like using ABS function)
Thanks

Hi bourasrafik, the strategy builder can not do arithmetic on the data it's given, the script would need to be unlocked to take the difference of the close prices.
