TIME FILTER

One of the things concerning me at the moment as a trader is the question if I should take all the tradesetups my system gives. I trade in a very distinctive timeframe: I only trade during the day and don't take positions overnight, so setups that occur after a certain hour I don't take.

The question is not a question about looking for an indicator filter. It is merely a point do I take another trade if my first trades were winners? Why take another another risk? Systemtically you should take the trade but is it worth the risk?

I am not a mathematician but suppose the system produces 10000 trades. You tested it with Monte Carlo or otherwise and it should give a nice profit. But wouldn't you expect that a random part of these trades, say 1000 trades, produce the same result?
I would think so.

But what if I sample all these 10000 trades in series which are determined by timeframes, say weeks or days. Would the result of such a sample serie, in the long run be the same as any other? That's the question I ask because if yes, this would mean that in any chosen timeframe it would be more profitable to stop after a winner or consecutive winners.
