Determining the fastest profitable timeframe for a low-frequency intraday algo for a retail trader?

I'm trying to come up with a general framework for this. The strategy enters actively meaning via market orders and pays the spread on each order.

Plus side - Average trade statistic of your algo
Minus side - transaction costs which include: bid/ask spread, commission, slippage
Overhead ratio = plus/minus

Then we need to aim for the fastest timeframe that produces a certain "comfortable" overhead ratio? What would be a good minimum ratio?

Anyone? :)
