I may be misunderstanding your question....

but if the market is doing this /\/\/\/\ it is a trading or ranging day



if it is doing this / you have yourself a trend...

now you also seem to be referring to some sort of forex equivalent to seasonality based on events and time..like Trader273 and brownsfan said, no way to predict the future, or else none of us would be trading....but if you were to conduct research and find high probability patterns on a calendar basis..there are those that trade that way and say it's the way to go.

I don't think this would be a good move in forex, but it's not my call, who knows you may come up with a way to blow the doors off the concept.

Good luck, hope I helped a little.
