It's fairly easy to do.
You need to define some user variables at the top of the triggers with value 0.
eg.
balance_t
trend_t and the same with -s suffix if you want to run the standard channel
Then first trigger:
set user variable balance_t Value: balance_t + last_wl
Exactly in R1 all selections Turbo channel
Conditions: Trigger Expression trend_t is equal or greater than 0.01 (or whatever)
AND: Channels Previous PL is not equal to 0
Then you can add your switch test mode on/off triggers using the channel_trend to activate them, but make sure the switch test mode off trigger is greyed out when testing.
Then your back or lay triggers if in R1
Next trigger:
Set user variable trend_t Value: channel_trend
Exactly in R2 all selections Turbo channel
No Conditions
Then other back/lay or green up triggers etc.
Before testing open the user variables window and add the variables:
balance_t
balance_s (if running standard)
channel_trend.
These balance variables represent a virtual balance which will be the same as the real balance if running live and switching test mode on/off using the channel_trend value.
IF you get stuck send me the backing/laying triggers you wish to use and I'll incorporate them into this system.
