How to test if we are on the latest bar ?

bobt · 2019-11-21T12:22:04+00:00

Hi, I am writing an indicator where sometimes I want to calculate against all bars, and sometimes only against the most recent bar. Effectively I want to be able to use “DEFPARAM CalculateOnLastBarOnly” but within an IF statement driven by a boolean variable declared against the indicator ( thereby allowing a user to control the output ). However, from what I can see the DEFPARAM can’t be placed within an IF, and so I need to code this for myself. How do I detect ( elegantly !! ), if I am currently working against the “current” candle ? This indicator can be used against ANY timeframe, and so comparisons against currenttime become quite messy, quite quickly. BarIndex effectively numbers from the beginning of the available bars – I need the inverse of BarIndex, so that I’m at 0 when on the current bar. Does anyone have any elegant solutions ? Regards, Bob

With the use of the new available instruction (only in version 11) : IsLastBarUpdate

Hi Nicolas,

Thanks for the quick reply – it’s good to know there is now a built in way of achieving this ( is full documentation of the new v11 commands available as yet ? ).

However, my users are mainly customers of IG, who have not rolled out v11 yet, and so I still need to achieve this the “old fashioned” way .. 🙁

If anyone has any good ideas, I’d be very grateful.

Regards,

Bob

The old way was by using this kind of condition:
```
IsLastBarOnChart=currenttime=opentime and date=today
```
