Using custom indicator for signals

[Seleucus]

Hey guys alittle help here , how can I make my EA read a return value from a getSignal() function in a custom indicator ?(like if getSignal function of custom indicator returns 1 when there is  a signal) 

How can I make my EA read that to know that there is a signal created and it can execute a trade.

With iCustom() can you get the buffer values of an indicator. Read the example even though there call an indicator the values of another indicator.

Of course you have to know which indicator you need and want (it must exist in compiled form) and what buffer has what kind of values.
