Trading strategy's and time frame.

Each strategy has his optimal time frame. A strategy can be profitable on 1 time frame and can be a loosing strategy on another timeframe. In a strategy its easy to detect the timeframe a strategy is running just by looking at the time of the start of a candle and the start time of the next candle. This way the strategy could be disabled if used in a wrong time frame......gives me ideas. In one of the next strategies i will use the time function.
