    Can I lighten CPU load this way?

    Back when I was using TradeStation there was a trick to save some CPU cycles in coding and I would like to see if it would work in NT (if I understand OnBarUpdate() correctly). This applies to CalculateOnBarClose = false; If OnBarUpdate() is "true" even if more volume comes in at the same price (changing Volume[0] but not Close[0]), then if I just check for a change in Close[0], I can skip the indicator calculations on all indicators THAT USE PRICE ONLY (not Volume) by immediately issuing a "return;" in the code. Of course, during highly volatile times Close[0] changes constantly, so not any savings there, but in "normal" times it might help - if it worked that way. Does it?

    You could save the current price Close[0] to a variable, then with CalculateOnBarClose = false; compare the Close[0] to the variable, returning if they are the same.

        I just tested that in an indicator and I get gaps.

          Hi eDanny,

          Perhaps you can contact Tarkus11 to see his implementation, as I have not tested this on my end.

            Sorry - I was specifically looking at this for minimizing calc time on my TPO chart (where I also have to account for the Initial Balance time if Close[0] doesn't change at that particular moment). For other indicators I'm not sure how it would work, though if the indicator is using # of bars (like an Average) you would obviously have to account for the new bar in the Average length (maybe using FirstTickOfBar or a counter as a flag...)
