EA needs to draw a symbol and/or line based on a OnTick()

[[Deleted]]

hi there!

can someone please give me a clue from where to start learning about graphical objects ?

to detect market acumulation, i have developed a function based on iStdDev(). 

everytime this function is executed i would like to draw a small line above and under the candlestick based on current price. i also want to draw an symbol !

what are the classes and libraries i have to look ?

regards

mrc
