Tomasz,
One of the reasons I would like to have a Gfx mode that plots above
the studies: see attached picture worth a thousand words.
It apears that the ordering of plots is (from bottom level to top
level):
Chart Background
Gfx (overlay mode 1) --FIFO
Plot Commands --LIFO or FIFO
Gfx (overlay mode 0) --FIFO
Study layers --FIFO
Gfx (the missing mode #1401) --FIFO
Cursor/crosshairs -- realtime layer
There have been a number of suggestions for layering of plots that I
do desire and support, but I am sure they will take a while to
architect and implement. In the mean time, this Gfx overlay mode
addition might be relatively easy to implement and with just one
sentence of documentation. I hope you can work it into one of your
betas in the near future.
Best regards,
Dennis
