NinjaScript > Language Reference > Common > OnBarUpdate()

Definition

Indicates if the incoming tick is the first tick of a new bar. This property is only of value in scripts that run tick by tick which is when the Calculate property is set to Calculate.OnEachTick or Calculate.OnPriceChange.

Warning: This property should NOT be accessed outside of the OnBarUpdate() method.

Note: If a bar type is set up to remove the last bar on a chart, IsFirstTickOfBar will automatically be set to True.

Property Value

This property returns true if the incoming tick is the first tick of a new bar; otherwise, false.

Syntax

IsFirstTickOfBar

Tip:

In NinjaTrader's event driven framework, bar closures are signaled by the tick that opens the next bar. The price of the last tick of a bar can be referenced by checking Close[1] on IsFirstTickOfBar. For volume and tick based bars, Bars.TickCount and Volume[0] can be referenced to see if the number of ticks / volume meet the criteria to build a new bar.

Examples


// On a tick by tick strategy the only way you know when a bar is closed is when // the IsFirsTickOfBar is true. protected override void OnBarUpdate() { // Only process entry signals on a bar by bar basis (not tick by tick) if (IsFirstTickOfBar) { if (CCI(20)[1] < -250) EnterLong(); return; } // Process exit signals tick by tick if (CCI(20)[0] > 250) ExitLong(); }
