Finding highest and lowest EMA

  Hi brains, I want to find the highest and lowest EMA between my current barindex to the previous tradeindex, but the following simple code returns nothing.

  Please advise what I have done wrong? Much appreciated.

  finding highest EMA

  EMA=exponentialaverage[10](close) HH=highest[barindex-tradeindex](EMA) LL=lowest[barindex-tradeindex](EMA) return HH as "HighestEMA", LL as "LowestEMA"

  1 2 3 4 5

  EMA=exponentialaverage[10](close) HH=highest[barindex-tradeindex](EMA) LL=lowest[barindex-tradeindex](EMA)   return HH as "HighestEMA", LL as "LowestEMA"

  TRADEINDEX is to be used in a strategy, not in an indicator.

  Yes, actually, I am using in a strategy, trying to debug.

  In my code, I actually used

  graph HH as “HighestEMA”

  Nothing came out.

  Thanks.

  Sometimes it is necessary to make sure you have enough bars before starting to calculate or nothing gets displayed. Try this:

  if barindex >= 10 and tradeindex <> 0 then EMA=exponentialaverage[10](close) HH=highest[barindex-tradeindex](EMA) LL=lowest[barindex-tradeindex](EMA) endif graph HH as "HighestEMA" graph LL as "LowestEMA"

  1 2 3 4 5 6 7 8

  if barindex >= 10 and tradeindex <> 0 then EMA=exponentialaverage[10](close) HH=highest[barindex-tradeindex](EMA) LL=lowest[barindex-tradeindex](EMA) endif   graph HH as "HighestEMA" graph LL as "LowestEMA"
