I have a code block that has a for next loop using i to index thru the data.. Is it possible to nest another for next loop with in it and use another variable say x to further ahead in the data? then revert back to where i was/is and continue? for instance:
For i As Integer = 1 To inputcount -1
if XYZ(i) = true then (looking for a pattern)
found = true
for x as integer = (i+3) to inputcount-1
< look ahead for price to be < the inputhigh(i).. look thru all the data for the first instance
next
end if <go back to i and look for another pattern>
next
I know this won't compile.. I am thinking conceptually.. also would it be possible to actually talk to someone regarding coding something?
Thankyou

Actually at first glance I think it will compile... but may or may not give you the results you want. First off, you will miss the first index in the array because you start "for i as integer = 1" instead of 0. Also, the second loop will not enter when i+3>inputcount-1, which if thats what you want is fine. Probably a safer way to do this would be like so:
if inputcount>=3 then ' make sure we have at least 3 values
for i as integer = 2 to inputcount-1 'start the index at the 3rd position
if XYZ(i-2) = true then 'look 2nd item back which will be 0 for first time through
found = true
for x as integer = i-2 to i 'loop through 3 indexes including current - first time through this would be 0,1,2
'look for whatever you want
if ABC(x) then
endif
next
endif
next
end if
if you want more than a 3 bar span then 3's = span and 2's = span -1

Thanks..but I guess what I am asking is can you have a for next loop indexing with "i" find a date and value then with index"x" scroll forward from that point in time( from i) and look for that same value?
and then return to the "i" for next loop and continue:
for i = 0 to inputcount -1
look for some thing and
if found ( call it buypoint)then
for x = i to inputcount -1
look for the buypoint again(only one occurance)
if found again then
addtooutput buypoint(x)
x=inputcount-1
end if
next
end if
next
something like that?

Sure...that should work.
Also, rather than set x=inputcount-1 to exit the inner loop you can just use "exit for"

OK Thanks...put that where I had x=inputcount-1?
