My (and many others') favourite exit is the Guppy Trailing Count Back Line Stop, G-TCBL, unfortunately it has a bug 😲 which I will demonstrate below:

1. As you can see from the attached To Do List, there is just one strategy, namely $Bug
2. This strategy is using a standard Connors RSI MOC order to enter trades but this is informational and largely irrelevant
3. The exit as you can see from the attached Trade Plan is a standard 3 bar G-TCBL (Guppy Trailing Count Back Line) MOC stop
4. As you can see from the attached details screenshot, the close (1) 455.91, is a proverbial country mile from the G-TCBL exit (2) 444.76. Even the low (3) 450.06, is an urban kilometre from the G-TCBL exit

As you can see there is a serious problem here …

Attached are the screenshots to assist with your problem diagnosis, please let me know if you require any additional diagnostics?

Cheers

The CBL indicator & the CBL Trailing stop are not exactly identical. Stops use additional settings that indicators don't & have to also factor in order types & other things. If you want to verify that a stop like this gets out when it should, plot the stops on your charts instead of the indicator & it should show correctly.

In your screenshot, it shows you're using the MOC order type & the close of the bar is 455.91. That is the price your exit was triggered, so this looks correct.

Why aren't the CBL indicator & the CBL Trailing stop identical? I can't for the life of me see why not?

According to Daryl Guppy's rules, https://www.guppytraders.com/cbl-info

RULES:
This is an end of day technique, so act only when there is a close below the count back line (Long side trading)

Use as a stand alone indicator as a protect capital stop loss.
…
…
…

In the attached screenshot:

1. The exit level is 450.06
2. Exit at 452.92
3. Close at 452.92

The trade exited with the close well above the exit level, this is a bug irrespective of order types, which IMNSHO will only determine whether the exit occurs on the current bar (MO or MOC) or the next bar (MOO)

I've written about this previously, so please correct me if my understanding is wrong: https://www.omnitrader.com/currentclients/proforum/thread-view.asp?threadid=8031

_________________________________________________________________________________________________

4. Back to my first question and an example of where there is a discrepancy between the exit and indicator

I've plotted the stop in red and the indicator in pink to differentiate their differences as they overlay each other

In the bottom righthand corner of the big box there is a discrepancy between the exit and indicator. The exit should have moved up to 443.71 instead of remaining at 440.68, this is another bug

Hi Barry

It's been over 7 weeks since I heard from Nirvana Support, is there any chance you could let me know when this bug is going to be fixed?

Cheers
