Re: unable to use barssinceexit(1) but able to print it [SOLVED]

Sorry bud, i think you’ve gotten in a muddle with terminologies there. Have a read up on open next bar.

To rephrase:

What event is triggering your code to calculate (e.g. Barstatus(1)=2)?

I was merely curious to see if non barstatus=2 calculation was to blame.

Out of interest what Bar Magnifier settings are you using in conjunction with this IOG backtest?

I suspect you've been stopped out at the next available data point (next bar open) which happens to be greater than your stop.

I would take a guess that your Bar magnifier setting isn't granular enough.

Re: Delays receiving real-time data

Are any users trading with MC12 r2 and not experiencing delays/lags?

This all sounds like an ongoing MC12 bug, no?

Multicharts; would you consider putting MC12 back into Beta and supporting MC11 again?

If a workspace is suspected to be corrupt; what's the quickest way to create a new one that is unlikely to also be corrupted?

I'm thinking copy and paste all charts from old workspace to a new one. Or will the new one inherit the same issue that caused the corruption?
