# Checking candle difference highs

#### jrlewis89

I want to create a watchlist indicator that compares two different times 5min and 15min to determine if the highs of each candle are different. I put together a code but it's not working properly any tips or suggestion?

Code:
``````def high5 = high(period = "5 min");

def high15 = high(period = "15 min");

def highDiff = high5 != high15;

# Add custom columns to display the results
AddLabel(yes, if highDiff then "yes"  else "", if highDiff then Color.GREEN else Color.RED);``````

Thanks

Solution
The code looks fine by eye. Most likely, the aggregation setting of the column is the culprit. Multi-timeframe references only go up, so you would need to set the column to 5min or lower. If not, let me know, I'll take a deeper look into it.

There's another thing you might want to account for though. Upon the opening of a new 15 min bar, there will also be a new 5 min bar, and the two will be identical for the first five minutes. So this sort of thing can only really come into play for the last ten minutes of each fifteen minute period.

Something like `high != highest(high,3)` while set to 5min bars might serve you better. It basically accomplishes the same thing, but it flows better than the multi-timeframe approach.
