  Yes you are correct (as long as yours "somefunction" 
  does not reference future bars).

    [Not sure if this made it through or 
    not. Didn't see any replies, and I need to know! Thanks,

    Say you want to make use of 
    indicators from multiple timeframes. Can someonetell me for certain if 
    code built like this looks into the future at 
    all:TimeFrameSet(inWeekly);MyIndicator = 
    SomeFunction(Close);TimeFrameRestore();MyIndicator = 
    TimeFrameExpand(MyIndicator, inWeekly, expandLast);buy = buy and 
    MyIndicator > threshold;sell = sell and MyIndicator < 
    threshold;My understanding from the docs is that TimeFrameExpand can 
    look into thefuture, but only if you use expandFirst. By using 
    expandLast, the weeklyprice isn't available until Friday, at the end of 
    the week, and looking intothe future is avoided.Do I have that 
    right? The code above doesn't look into the future, even bypart of a 
    day, 
ever?Thanks,Dave
