I am trying to develop an indicator based on the 1 minute Heikin Ashi with the 5 minute Heikin Ashi bar as confirmation of trend. I am trying to determine how I can calculate the 5 minute HA values from within the 1 minute chart - anyone able to help? I have the following code which uses the two aggregations, but this is not allowed when creating alerts or scans. So I am looking for some help on how I would manually calculate the 5 minute using the 1 minute data and not reference two different time periods:

Code:

```
#### Start Agg1
input agg1 = AggregationPeriod.min;
def o1 = open(period = agg1);
def h1 = high(period = agg1);
def l1 = low(period = agg1);
def c1 = close(period = agg1);
def haclose = (o1+h1+l1+c1)/4;
def haOpen = if haOpen[1] == 0 then haClose[1] else (haOpen[1] + haClose[1]) / 2;
def haHigh = Max(high, Max(haClose, haOpen));
def haLow = Min(low, Min(haClose, haOpen));
def trend1 = if haClose > haOpen then 1 else if haClose < haOpen then -1 else 0;
#### End AggTime1
#### Start AggTime2
input agg2 = AggregationPeriod.Five_min;
def o2 = open(period = agg2);
def h2 = high(period = agg2);
def l2 = low(period = agg2);
def c2 = close(period = agg2);
def haclose2 = (o2+h2+l2+c2)/4;
def haOpen2 = if haOpen2[1] == 0 then haClose2[1] else (haOpen2[1] + haClose2[1]) / 2;
def haHigh2 = Max(high, Max(haClose2, haOpen2));
def haLow2 = Min(low, Min(haClose2, haOpen2));
def trend2 = if haClose2 > haOpen2 then 1 else if haClose2 < haOpen2 then -1 else 0;
```
