SampleEnterOnceExitEveryTick

[dvercher]

I have some doubts in this sample strategy,

I don't get if (Historical) return; Wha does this part of the code mean?

The other thing I don't understand is the meaning of FirstTickOfBar, Wouldn't be the same if we just write if Position.MarketPosition==MarketPosition.Flat??

Thanks

Hi Daniel,

I don't get if (Historical) return; Wha does this part of the code mean?

This is used to enforce "real time only" operation of the script. If the bar is historical, then it returns out of OnBarUpdate, preventing any further processing. It only processes if the bars are real time.

The other thing I don't understand is the meaning of FirstTickOfBar, Wouldn't be the same if we just write if Position.MarketPosition==MarketPosition.Flat??

This property identifies the first tick of each bar. It's only true for the first tick of each bar and all subsequent ticks for this bar would return false. It is not connected in any way to position updating in a strategy.

Thanks for your reply,

So every strategy using tick information must be run in real-time, is that correct? If I make a backtest, wouldn't I have any results?

One mpre thing I forgot, in SMA, if I don't specify Close,High, Low, Open, which one takes into account? For example SMA(10)

Correct -- There is no tick by tick sequencing that can distinguish a first tick of bar in a backtest. But for historical (Backtest) bars, FirstTickOfBar will always be true.

It's the if (Historical) return; part that would make this not work in a backtest.

The default input for SMA is Close.

Hi Zigman,

That sample is available here for separating logic to calculate on bar close or each bar update:
