How does Ninja make 3 day charts / EMA's

[T2020]

In each 3 day chart the brown or dashed line is the 34 EMA . It would have
been a trading signal on the Ninja chart ,but which chart is right or how does
Ninja figure MA's on the 3 day chart ?

Hello T2020,

Different data feed providers can have discrepancies in their data, please see the link below for more information.

Different data will cause different SMA values as well.

You can go to Tools-->Edit NinjaScript-->Indicator and double click the SMA indicator to check how the SMA is calculated.

Hello T2020,

From your links , it looks like your 3 day chart is build from daily bars and I'm
sure the same is true of the other vendor . That's quite a discrepancy . Looks
to be 5 points or more . This doesn't really provide an answer . Without an
expert on both software's , there probably isn't any .

If you have time , could you post a 3 day chart of SPY using esignal ,with a
34 EMA on it ? I would like to see if there's much of any difference between
them and what I have which is Barchart . Tia .

Thank you much . I can see Esignal and barchart are fairly close . I'll have to
assume the other software is the problem .
Thanks again .

was very close .
