Using the price level of a teminal implemented Horizontal Line

[Henri]

Surely this can be done right? Reading the price level

of a user installed horizontal line. By user installed I mean

placed on to a chart manually.

The following code is something i was playing with trying to learn to do just that.

In the end i want to be able to place 2 Horizontal lines on a chart

and have my indicator calculate their pip difference.

From there i would calculate a number of other items of interest.

SL as a percentage of equity, max number of Units i could trade as a % of equity,

and other risk management concerns.

Problem is I am a very new programmer i cannot get the program to pick

up the NEW price once I move the h-line on the chart. As if the system ran once and was done.

Doesnt it cycle?

The code represents a number of different efforts to get to the data. It is simply a

test program to try to learn how the objects work so there are many extraneous lines.

Your help in any fashion is MOST appreciated.
