3 Semafor Alert questions

Hi,

I would like to know if the attached indicator - "#4X 3 Semafor Alert" repaints on previous and closed bars?

I think it repaints if new highs/ lows are reached, but does it changed the previous highs / lows into levels 1 or 2? or does it delete the signal altogether?

The reason is I am doing back testing on this indicator and I'm afraid I am not getting the correct signals.

Thanks for your help in advance.

This is a fairly good article about how to do it yourself in determining whether an indicator repaints.

As far as I can tell it repaints on everything.

You can check this yourself very easily.
1. Put it on a H1 or M30 chart and mark it with an arrow or price tag when you get the alert an see how far it moves.

2. Use the Strategy Tester.
Toggle the Strategy Tester Icon form the toolbar.
Select an EA from the popup
Select a Pair form its popup
From the "Model" pop select "Every Tick"
Tick the boxes Use Date and Visual Mode.
Select a date from the "From" popup
Do the same from the "To" popup
Make sure the slider to the right of the Visual Mode checkbox is all the way to the right.
You can ignore the "Skip To" popup

Select Period from the popup
make sure the Optimization checkbox is not ticked

Click Start

Wait for the Strategy Tester to begin running(this should be less than a minute)
As soon as it starts drop you indicator on the chart.
Now you can see how it will behave in Live trading.

Thanks for your help.
