Help with Counter script

[AssassinAR15]

Hello! I have been searching the forum today in search of a script that will count the number of times something has occurred during a specified time period.

After reading through dozens of threads, I could not find anything that parallels what I am looking for. I did play with a few scripts, but was unsuccessful in getting it do return what I need.

For example, I want to know how many times SPY had a volume candle above 500k at any point from pre-market open to 7:59pm est. Then from there, just have that number in a watchlist column.

Hope this makes sense, and any help would be appreciated!

Thanks!

you can do that something like this: (I'm typing this here in useToS, not in the code editor so there may be typos)

def start = 0000;
def end = 0800;
def volume_threshold = 500000;

def in_time_window = if secondsFromTime(start) > 0 and secondsTillTime(end) > 0 then 1 else 0;
def volume_above_threshold = if volume > volume_threshold then 1 else 0;

def counter = if in_time_window == 1 and volume_above_threshold == 1 then 1 else 0;
plot condition_met_count = sum(counter, 50);

This is all much easier if you don't need the time window, and I don't know how many bars would exist in your chart or column for the pre-market (this would be necessary for the length of the sum counter... if it is too short, you'll clip the front end of the counter, and you'll see the number decrease over the day as less and less of the window is counted (as the chart moves forward)).

Perhaps this gets you going in the right direction. It's always better coding to be explicit (that's why I use 1 and 0 not just assumed false if not true kinds of things) and I always try to define my conditions as separate statements.

Thank you so much @mashume !! The time does not matter per se, just as long as I am able to capture PM data.
