ADX of Previous Bar

[NinjaCustomer]

Hi,

if i do ADX(Input, 14) then I will get the ADX of the current bar.

How do I get the ADX of the previous bar?

NinjaCustomer, this code will get you the ADX of the current bar:

double current_ADX = ADX(Input, 14)[0];

and this code will get you the ADX of the previous bar:

double prev_ADX = ADX(Input, 14)[1];

As you can see, it is simply a matter of changing the number in the square brackets to go even further back if you wish.

Doesn't work

Here is the whole of my indicator (that I made to illustrate the problem):

The code that displays the fixed text "right" does not get executed

I'm using 6.5

You would need to make sure to not access any undefined bars at the OnBarUpdate() start -

Your code below likely throws an error to the log tab....
