Suppose I write a custom indicator Foo that uses multiple timeframes (say its input timeframe, plus 5min and 15min bars) internally. If I then use it inside a strategy (or another indicator) that runs only on 1min bars, will the strategy have any awareness or concern with the 5min and 15min bars, or be affected by them at all ? I think the answer is no, which means that the multi-timeframe messiness is confined to the Foo indicator. Please confirm this.
Obviously the strategy is not going to be able to work until the Foo indicator gets enough bars (e.g. the 15min ones). Are there any other subtle effects (e.g. session templates) ?
