Cant run backtest

[zooinek]

Hi,
i would need an advice if you can..
My NinjaTrader can not run backtest in strategy analyzer.
When i start NinjaTrader there is everything all right and everything works..
when i click File - new - strategy analyzer then i choose any market (for example ER2 ##-##) and right click and choose BACKTEST then will everything stop... ninjatrader freeze (iam not sure this is the right term..) ..nothig works and i have to restart ninjatrader.

But 2 days ago it worked corectly and i was using backtest for 2 months..
but since yesterday it doesnt work.

Could you help me?
Thank you

Please try on minute charts with the SampleMACrossOver. It sounds like you are either backtesting too long a period or your strategy is in some sort of high CPU intensity calculations while backtesting.

But i can not run the backtest window...
i right click ER2##-## and left click Backtest and then is CPU Usage 100% and nothing happens...

i can not open <a href="http://www.cannontrading.com/images/ninja-trader-TradingSystemDevelopmentBacktesting_StrategyAnalyz er.png">this</a> backtest window. When i am trying to open the window (right click ER2##-## and left click Backtest) it stops everything, nothing works and the window is not opening

it happend to me on two different computers in the same day

P.S. sorry for my english

zooinek, the ER2 is an old contact, this would be now the TF - can you retry with this one?

Also: which NinjaTrader version are you using? You can check this under Help > About.l

[zooinek]

i have version 6.5.1000.7
i know that ER2 is an old name and now it is TF but i had old historic data from 2007 and there it was ER2...
but thats not important.. the backtest window is not working on ER2 and also on FESX 06-08 ... i have no more historic data.

It worked on ER2 and on FESX on both computers few days ago and now it is not working. It stopped to work on both computers in the same day. On the both contracts which i have (ER2 and FESX).

Thank you

zooinek,

One reason you may hit 100% is if there was some runtime errors in a script somewhere on your system in the Initialize() method. Please remove all custom strategies and then try again to see if you can bring up that window.

Please also upgrade to 6.5.1000.10. Thank you.

[zooinek]

Yes its working now..
i removed the last custom strategies..
now i import the strategies back..
theese two strategies has this initialize method:

protected override void Initialize()
{
CalculateOnBarClose = true;
ExitOnClose = true;
Add(PeriodType.Tick, 1);
EntriesPerDirection = 10;
EntryHandling = EntryHandling.AllEntries;
}

So are you still having issues? Adding a 1 tick time frame is VERY resource intensive on your computer. Depending on the time range you try to select you may run out of memory to hold such an extensive data set.

[zooinek]

is there any other way how could i get informations about every tick?
when i am programming any strategy and i need to enter long every time, when price is crossing my line line1
so i made:
if (BarsInProgress==3) { // 1 tick time frame
if (Close[0]=>line1 && Close[1]<line1) {
EnterLong();
}
}

zooinek,

Unfortunately not. Backtesting just doesn't have the granularity you are looking for. If you want every tick you should forward test instead. Please try using Market Replay or just test against real-time data.
