How to prove an automated strategy

[tattydon]

Firstly, hello - I’m new here so apologies if this has been asked before or is unclear

I am still trying to digest information and am keen to use automation to trade ultimately. Being a hobby coder, that area interests me more than trying to trade bounces and continuations which Peter is clearly so good at.

My question is ‘do any of the shared automations work?’. I’m not looking for the magic answer but more trying to work out how you guys back test any of them. If I take the old strategy of 15:40 in Tennis for instance, how do you know that that isn’t already factored into the market as I gather it is these days? Put another way, what are you comparing it against to be sure that you are finding value in the long term?

If there is no backtesting, is it purely a matter of coming up with an idea: e.g over 3.5 is underpriced at 80 minutes if 1:1. Then automating it and hoping for the best?

Thanks in advance
John
