Use mouse functions to edit signals in realtime ?

Hi,
I would like to use new mouse functions to edit on the fly in realtime parameters of my signals.
I'll try to explain. Let's simplify. Suppose you have a signal that you use as a trailing stop. For instance you are long and use a low[1]-n*atr(14) to trail and stop your position.
N is your input multiplier that you can edit with format signal.
On an other java platform I use it is possible to draw text or buttons on the chart that when clicked execute a function. So in our case I could draw button plus that when clicked would increment n in realtime without having to format signal.
With multicharts does it exist the possibility to achieve the same feature ?
Eventually with any add on?
Thanks in advance
Massimo

It is possible... but will take some programming.

You can draw a text object on the chart, then have the strategy to read the text object to modify your logic.

Hi TJ,
thanks for your advice.
Probably Text_GetActive can be useful for my feature.
I'll try to understand how to use it.
If anyone has an example, please post it.
