Unfortunately for Arakne (and its current subscribers), this is a good point.

One of the fundamental weaknesses of any backtest is curve fitting and over optimization bias, where the strategy producer adjusts the parameters to produce the absolute best results for a given set of data points, which does not necessarily provide any real trading edge, but simply provides a coincidental configuration for excellent results over a given past time period...

Contrary to popular opinion, however, Cryptosparks is a smart guy and has some strong insights into algorithmic trading  , so I hope these live experiments by veteran BTT users can be a good opportunity for him to enhance his trading and developing skills.
