PFE indicator

[opstock]

Could someone who understands .efs better than I do, take a look at this formula. Its real time plotting changes if you reload it. I really like this indicator. It would be great if someone could get it to plot correctly in real time.

Thanks for any help!

Re: PFE indicator

Steve
The reason for the behavior you are seeing is due to an incorrect placement of the routine that assigns at each new bar the values of EMA to EMA_1 which needs to be placed before EMA is calculated and not after
If you search the forums for the keyword PFE you should find a thread related to this issue as it has been discussed in the past IIRC.
As an aside you will also find more up to date versions of the same indicator

Great, Thank you Alex. I searched for it before, but could only find the same old version. I wasn't searching in the right forum, I guess.

Thanks again,
