How to strategy test against multi timeframes ?

[wcredle]

How do I take a strategy and after beacktesting it, them run the optimizer using many different time frames? Restated, I run a successful backtest, get a good result lets say using 10 minute charts, I can manually set backtest to 15(or 4 or whatever) and run it again, how can I set a range of minutes ( 1 to 30) or whatever, and get the optimizer to find out the most profitale period for my strategy. PS I know how to set a "slow" / "fast" MS variable and have optimizer run against all combinations, can't seem to figure how to do same with minutes.
Thanks
