Hi…
Depending on complexity of what your trying to do, the following could be an alternate option is some cases.
Basically, add a custom indicator, call it ‘MAIN’, that only contains a ‘CALL’ to another custom indicator let’s say ‘DATA’.
Add ‘MAIN’ to all desired charts.
Now the code in ‘DATA’ will run in all charts (price or stand alone) that contain ‘MAIN’.
Therefore the code in ‘DATA’ runs on all MAIN’s and if you modify ‘DATA’ and update it via the ‘ADD to indicator’ button, the changes are replicated onto all the charts. On the next tick event I think.
Since, number of bars,barindex,intradaybarindex values are going to be different on different timeframes, using the x an y scale value of time and price, which appear the same on all charts, allows certain drawn objects to appear on all charts.
Below are some simple examples of what could be achieved.
Things to note, IMO, are:
PRT appears to be an EVENT driven system, and the events are ‘ticks’
For a bar to exist it needs a ‘tick’
Code runs at the end of each bar.
NO tick/bar, no bar, no run code, no update.
