Count green candles

[bwca]

Hi all,
For opening drive plays, I find the more green candles, the stronger the drive/scalp.

I'd like to create a column on my watch list, that counts the number of green candles (3min in my example) of the first 30min of the day.

I can code 1/2way decent in thinkscript, but, what I don't know how to do, is get reference to individual candles.

I was wondering if someone could point me in the right direction.

Thanks a bunch!

I found this script sometime ago in this community as a watchlist column.
You can create a watchlist column and set the aggregation to 30 minutes.

def grn = close > open;
def red = close < open;

def cnt;
if grn then {
cnt = fold i1 = 0 to 100
with p1
while getvalue(grn, i1)
do p1 + 1;
} else if red then {
cnt = fold i2 = 0 to 100
with p2
while getvalue(red, i2)
do p2 + 1;
} else {
cnt = 0;
}

plot z = if red then -cnt else cnt;

AssignBackgroundColor(if grn then color.green else if red then color.red else color.gray);
