Sabrina Pepe:

There's a lot that you're asking for, but it comes down to using the ChartEvent CHARTEVENT_OBJECT_DRAG.

When the event is fired, check the sparam of OnChartEvent() to make sure it matches the name of the HLine . If it does, then get the HLine's OBJPROP_PRICE value and set it to the Fibo's OBJPROP_PRICE1 or OBJPROP_PRICE2 value, whichever is the 0 level of your Fibo.
