Automated Testing Script

Hi there guys,

 I am looking for a script to test out possible strategies.

An example scenario would be:

If RSI is more than 70% then wait for it to come back down past the 69% point, place a fake trade instantly, close trade exactly 5 minutes later.

The idea behind it is that I'd like to be able to test months of data using the same strategy and then report the prices and how many times it would have been correct/wrong.

I'm not sure if this is even possible, so thank you for the patience! :)
