Re: [amibroker] Do all trading systems stop working? - Howard Bandy's book

["Mubashar virk" <mvirk67@xxxxxxxxx>]

Dr. Bandy might have theorized on the probability of mathematical exhaustion of the trading systems. Such a possibility indeed exists: keeping all else equal, if one start counting forward from 1 then one should be able to count till the last number.

 

However, in practical term there should not be an end to the trading system evolution and adaptation.

Subject: [amibroker] Do all trading systems stop working? - Howard Bandy's book

All,

In his really good book Quantitative Trading Systems, Howard states that all trading systems will stop working forever at some point (because the inefficiency in the market they exploit will be killed by everybody jumping on board).

On the other hand you have momentum / ROC based systems working forever now, same for trend following MA crossover systems like The one propagated by Mebane Faber. Momentum and MA rossover trendfollowing does seem to work "forever".

Any comments from the gurus here?

Thanks, Samantha
