Hi,

I’m trying to write and indicator which will, for example, add 30 moving averages to a chart in sequence from 1 to 30 but I’m not quite how to code this.

Can someone please help? My attempt below obviously doesn’t like the RETURN statement in the FOR NEXT loop.

Thanks

Rob
```
FOR i = 1 TO 30 DO
a = average[i](open)
RETURN a as "Average"
NEXT
```

There are some limitations because of the “infinite loop” error, but this kind of code could make the trick:
```
defparam drawonlastbaronly=true
defparam calculateonlastbars=100

//--- settings
lookback = 50 //periods to plot
firstPeriod = 1 //first moving average Period
lastPeriod = 30 //last moving average Period
//--- end of settings

b = 1
for i = max(1,firstPeriod) to max(1,lastPeriod) do
for a = 0 to lookback do
drawsegment(barindex[a],average[i][a],barindex[a+1],average[i][a+1]) coloured(0,191,max(1,255-b))
next
b = b+5
next

return
```
Because, it is not possible to draw curve in the past, I used segments instead. You can choose the MA’s first period to last period to be plotted. First time I made a Guppy / Fishnet indicator like this 🙂
