Convert a simple mq4 Indicator to an Expert Advisor with two additional Features

Hi,

I have a very simple trend indicator (50) lines of code. I would like to convert it into a simple expert advisor. The trendline must be shown on the chart (if possible), like with the original indicator.

Once converted:

1. The EA must set three orders (sell or buy depending on indicator) with three TP targets, 20, 50 and 150 pips.

2. The orders must be closed on opposite signal (given by indicator).

PS: I do want to use the indicator as a resource, I want to embed it within the EA.

Very very easy job.
