Bars reprocessed when using custom bar type

[saltminer]

Hi,
I've converted a custom bars type from NT7 to NT8. At times this bar type removes the last bar and creates a new one. In NT7 this is fine and no problems. In NT8 however, it causes an OnBarUpdate() event and IsFirstTickOfBar is true.
What this leads to is a reprocessing of a past bar. See this print out issued at IsFirstTickOfBar == true;

The code used for this print out (in an indicator) is

if (IsFirstTickOfBar) 
					Print(Time[AZ]+" FirstTickOfBar of index "+CurrentBar+" of "+Count);

(This is realtime and Calculate.OnEachTick and AZ equals 1).
I am getting THREE first tick of bar events at once:

22/09/2016 4:44:33 PM FirstTickOfBar of index 1206 of 1209
22/09/2016 4:44:44 PM FirstTickOfBar of index 1207 of 1209
22/09/2016 4:45:08 PM FirstTickOfBar of index 1208 of 1209
22/09/2016 4:44:44 PM FirstTickOfBar of index 1207 of 1210
22/09/2016 4:45:08 PM FirstTickOfBar of index 1208 of 1210
22/09/2016 4:45:30 PM FirstTickOfBar of index 1209 of 1210
22/09/2016 4:45:08 PM FirstTickOfBar of index 1208 of 1211
22/09/2016 4:45:30 PM FirstTickOfBar of index 1209 of 1211
22/09/2016 4:45:44 PM FirstTickOfBar of index 1210 of 1211

Hello saltminer,

Development has looked into this case. May we test your NT 7 Bar Type, NT 8 Bar Type, and your test script on our end?

You can find the NT 7 Bar Type under Documents\NinjaTrader 7\bin\Custom\Type.
You can find the NT 8 Bar Type under Documents\NinjaTrader 8\bin\Custom\BarsTypes.
And the test script would be under Documents\NinjaTrader 8\bin\Custom\Indicators.

Please send these over to platformsupport[at]ninjatrader[dot]com with 'ATTN: Patrick H - 1576825'.

Please let me know if you have any questions.
