'OnBarClose' acts lik 'OnPriceChange'

Hello,

I have Calculate= Calculate.OnBarClose in the SetDefaults state but OnBarUpdate() executes whenever price changes. Why is that ...? Thanks for the help.

Check Calculate in strategy settings.

Oh yes, the setting in strategy is OnPriceChange. Thanks. Any way to override the setting upon the script running so I dont need to check here and there?

In State.Configure or State.DataLoaded you could just add the line "Calculate = Calculate.OnBarClose". What this does, basically, is that if the user changes it to OnPriceChange, it changes it back. You also, potentially, could hide that input in the user interface so that the user of the strategy cannot change it, especially if it is overwritten in the code.

If this were not a strategy but an indicator, you have to be more cautious, in that if you develop an indicator that only works with OnBarClose yet someone else builds a strategy that hosts your indicator and the strategy runs OnPriceChange or OnEachTick, NT will force your indicator to run in that same calculation mode. For that situation, if it is not practical to "fix" it so your indicator works intrabar, I would recommend that you throw an exception e.g. "if (Calculate != Calculate.OnBarClose) throw new Exception(this.Name + " only works with Calculate mode OnBarClose");" so at least they know what's wrong. What you should definitely NOT do is pretend like that isn't a possibility and just blaze forward assuming everyone will leave it at OnBarClose.

Clear. Thank you Bruce. /Steven
