Finding lowest volume

[CapitaineFlam88]

I want to find the lowest volume on 1 min chart. Then have that volume candle change color or indicate with an arrow,.

Thanks

you can use the lowestall() function and call volume as the argument:

def LowestVolume = LowestAll(data = VOLUME);
AssignPriceColor(if VOLUME == LowestVolume then color.red else color.gray);

LowestAll() and highestAll() tend to get complaints about complexity from ToS however, and so using Lowest() with some really long length might be more performant.

Happy Trading,

Thanks. I guess I need probably the last 30 min. That should make the script lighter.

I am using lowest. but what happen is if there is less than 10 bars it won't detect. It want to have 10 min of trading since the opening 9:30 am. Is there a way to count the number of bars since opening?

input length = 10;
def LL = Lowest(volume (period=aggregationPeriod.min), length);

1. maybe you should start over and restate what you are trying to see, you asked for 3 things so far.
don't make guesses on methods, like counting bars or detecting bars, just state what you want to see.

2. there will always be more than 10 bars of data, unless you are looking at a stock 1 minute after an IPO.
do you mean you don't want to look back into yesterday to find the lowest bar? to only use the data in 1 day.
at 9:31 lowest( volume, 10 ) would look at some bars in yesterday.
if so , then maybe you want the first time this runs is at 9:39? lowest(volume , 10)

3. or maybe this ? find the low each day
def agg = AggregationPeriod.DAY;
def lo = volume(period = agg);
... if lo == low then ... do stuff

4. 2nd aggregation can't be less than chart time.
1 minute is the smallest chart time.
there is no reason to set 2nd aggregation to 1 minute.
if you want 1 minute data, the chart has to be set to 1 minute.
