As I've said a billion times... my only aim is to make profit for myself and investors. That is the end goal. If it is being met by the script, I'm happy with the script. Naturally if I ran this for too long a time in one shot, it would make losses, so I have to run it in short intervals while it watches for green trains/red trains.

You can stop applying maths to a script which you have not seen. It is impossible to do so. You never know, I might be sitting on some Nobel Prize material. I will continue making a 20% ROI daily for the next year. Just look at my stats! You'll see it
