Can you use for statements for automated trading, where each indicator refers to the last bars value?

Just a random example:
```
once x=0
ax = x/3*abs(x-5)

x=x+1

if barindex>100 then
a=0
b=0
c=0

for i=1 to 100
a=a+ax[barindex-i+1]
b=b+ax[barindex-i+1]*i
c=c+ax[barindex-i+1]*i*i
next
endif

indictor = a*b/c

if close crosses under indicator
buy n contracts at market
endif
```
Doesn’t seem to work for me.. Is it allowed?

Could it be that you spell ‘indicator’ differently on row 18 and 20?

Good eye! But sadly, no.. It’s just an example I made up now.

What is the error message you receive, if any? Is there a value returned for a, b and c? Does it work with say, 30 iterations instead of 100? Could it be the close cross under indicator check that does not work?

Literally nothing happens, I get the summary (but no trades). And I tried all kinds of conditions apart from ‘cross under’.

Use the ‘graph’ function and check how each of your variables behave.

They are displayed correctly; that’s the weird part.

Do you define all your variables from the start, and have you tried for example defparam preloadbars=1000? Also, isn’t the value of ‘indicator’ much greater than the close price? I don’t think there is anything wrong with your method or the for statements here, but rather the example you have. Here is for example an indicator I have made that uses for statements to gather data from previous bars: https://www.prorealcode.com/topic/pattern-matching-price-movements-in-prt/
