multi time frame EMA

[td_910]

Hi,

I tweaked a multi time frame EMA indicator a bit. Depending on chart TF it throws errors. I think it has to do with the number of bars loaded in the chart.

Any help appreciated.

Cheers

Hello td_910,
I can run the indicator fine at my end. Can you please let me know the exact steps to replicate the scenario.

I look forward to assisting you further.

Hi Joydeep,

it's regarding this line:

if (CurrentBar < 800) return;

I did trial and error to come up with 800. I had 200, but this gave errors for sessions with larger bar numbers. E.g. RTH 5min (81 bars) always worked fine with 200, but everything with more bars like ETH does not. ETH seems to work with numbers >270.

How do I calculate an exact number? Is there a way to have this a more "correct" code?

Cheers

Hello td_910,
Thanks for the information.

If you replace the code with the below code then can you get the indicator to work.

if (CurrentBars[0] < 1 || CurrentBars[1] < 1 || CurrentBars[2] < 1) return;

Please refer to this post which discusses in further the reason for the errors

Hi Joydeep,

many thanks. It works. But what is the difference to:

if (CurrentBar < 200) return;

Doesn't this line of code does exactly the same, because it is called for all Bars objects (0, 1, 2) ?

Thanks

Hello Thomas,
No, they are not the same.

You can have 200 one minute bar, but that does not guarantees you that a daily bar has formed. However you are trying to access a daily bar (with Closes[2][0]). This will throw an error.
