Free Trial Indicators

Hi everyone,

I want to share with you free trials of my 3 main indicators. I would really like to hear from you what you think of these indicators.

Are they easy to use?
Did you get any errors?
Is there any thing you would rather I change?

The indicators are attached below, but if you want to know more about how to use them:
