Nothing ventured, nothing gained?!

Some days I may not identify any stocks to buy - should I reduce my threshold of requirements and in turn increase the risk to undertake the purchase - as said nothing traded, nothing gained - but equally nothing traded, nothing lost - and perhaps some trading days I should take the day off as it were.  Use it for researching for the next trading day.

I think changing requirements for the sake of a trade is not wise as it loses the discipline of picking stocks that meet specific criteria - likewise looking for trades of greater profits to make good losses or non-trading days is to be avoided.

In these Bearish times better to wait out the day for the next trading opportunity.
