Time exits

[staycool3_a]

		
private int entrytime=0;
private int currenttime=0;
private int diff=0;

			currenttime=ToDay(Time[0]);

			//reset times
			if (Position.MarketPosition == MarketPosition.Flat)
			{
								entrytime=0;
								currenttime=0;
			}

			//store entrytime
			if (Position.MarketPosition == MarketPosition.Flat 
				&& CurrentBars[0] > BarsRequiredToTrade
				&&CrossAbove(SMA1, SMA2, 1))
			{
				EnterLong(Convert.ToInt32(DefaultQuantity), "");
				entrytime=ToDay(Time[0]);
			}
			
			//calculate difference between entry time and current time in a position
			if (Position.MarketPosition == MarketPosition.Long);
			{
				diff=currenttime-entrytime;
				Print(diff);
			}
			
			//exit after 5 days and reset entrytime and currenttime
			
			if(diff>5)
			{
				ExitLong();
				entrytime=0;
				currenttime=0;
			}

Basically I am storing the date for my entry (similar to how it would appear in strategy analyzer trade report) and then exiting after 5 days have passed.

Thoughts on this code? Looks like it works fine. Is this an efficient way to keep track of time? I could use barssinceexecution but I can't for my purposes. Asking b/c my strategy has thousands of lines of codes and trades up to 5 instruments at the same time so trying to reduce the code as much as possible.

It is fine. I doubt it will run any faster if you alter it a little like this:

			currenttime=ToDay(Time[0]);

			//reset times
			if (Position.MarketPosition == MarketPosition.Flat)
			{
								entrytime=0;
								currenttime=0;
			}

			//store entrytime
			if (Position.MarketPosition == MarketPosition.Flat 
				&& CurrentBars[0] > BarsRequiredToTrade
				&&CrossAbove(SMA1, SMA2, 1))
			{
				EnterLong(Convert.ToInt32(DefaultQuantity), "");
				entrytime=ToDay(Time[0]);
			}
			
			//calculate difference between entry time and current time in a position
			if (Position.MarketPosition == MarketPosition.Long);
			{
				diff=currenttime-entrytime;
				Print(diff);

			
			     //exit after 5 days and reset entrytime and currenttime
			
			     if(diff>5)
			     {
				ExitLong();
				entrytime=0;
				currenttime=0;
			    }

			}

Thanks! Btw I see you're in DC. I'm always there. We should link up!

Actually ended up using barssinceexecution

				AddDataSeries("USDCAD", Data.BarsPeriodType.Minute, 90, Data.MarketDataType.Last);//15

			if(TimeStop == true)
			{
			if(BarsInProgress==11 && Positions[11].MarketPosition == MarketPosition.Long && BarsSinceEntryExecution(11,"nzdb1",0) >= 96)
			{
				ExitLong(Convert.ToInt32(Position.Quantity), "nzdtimestop", "nzdb1");
				ExitLong(Convert.ToInt32(Position.Quantity), "nzdtimestop", "nzdb2");				
			}

				ExitLong(Convert.ToInt32(Position.Quantity), "cadtimestop", "cadb1");
				ExitLong(Convert.ToInt32(Position.Quantity), "cadtimestop", "cadb2");				
			}
			}

additional information: i have a bool for each instrument so i can "turn on/off" a particular instrument within the strategy. when i turn off the instrument, it does not generate any trades, when i turn on the instrument, it generates trades.

my primary instrument is using 90 minute bars. and so is all additional instruments (see above).

problem:

if i only turn on 1 instrument, the strategy exits the trade as expected after 96 bars (see BarsSinceexeuction code above). however, if I turn on more than 1 instrument, for some strange reason, the TimeExit is being initiated after 3 hours. All of my trades end up exiting after 3 hours. Why is this happening?

Does barSinceExecution work on multiple instruments? Are my indexing for barssinceexeuction correct?

found the solution:

https://ninjatrader.com/support/helpGuides/nt8/en-us/?welcome.htm

barsInProgressIndex- The index of the Bars object the entry order was submitted against.

Needed to change the index to match appropriate dataseries (1:5) bc my entries are on tick data.

Hello calhawk01,

Thank you for updating this thread with your solutions.

hi

for some reason same code is generating different results in market replay vs strategy analyzer

i have

		AddDataSeries(Data.BarsPeriodType.Minute, 14);//5

then timed exit:

			if(Position.MarketPosition == MarketPosition.Long
				&& BarsSinceEntryExecution(1,"Target1S",0) >=1)
			{
				ExitLong(1,Position.Quantity,  @"STP1",@"Target1S");	
				ExitLong(1,Position.Quantity,  @"STP2",@"Target2S");	
				ExitLong(1,Position.Quantity,  @"STP3",@"Target3S");	
			}

I am subimitting my orders at the above mentioned data series of 14 minutes. but I am generating my orders based on [0] data series, [0] data series = 1440 minutes.

for some reason during my backtests on strategy analzyer; my exits are:

entry time:10/4/2017 18:38
exit time: 10/8/2017 17:14

notice the above are about 4 days apart.

during market replay; my exits are following:

entry time: 10/4/2017 18:10
exit time: 10/5/2017 17:00

**note both above "entries" are same exact but one is from market replay and the other is from strategy analyzer.

why is the same BarSinceEntry logic behaving differently during strategy analyzer and market replay? I have: "Calculate.OnEachTick;=true"

thanks

Hello calhawk01,
Thanks for your post.

The Strategy Analyzer does the best it can to simulate the real market but it is not perfect and it works on bar closes instead of every tick. It would be expected for a strategy running real-time to produce different results than the performance results generated during a backtest. In this case, using Market Replay would be akin to real-time.

Please review the following help guide documentation that discusses the differences between Real-Time strategy results vs Strategy Backtest results.

Please let me know if you have any further questions.

[staycool3_a]

Did you seriously just response stating that there are discrepancies between backtest and replay, in response to my question? I'm much familiar with the discrepancies... is this another one that I have to add to the list?? Exits that are FOUR days apart due to barsinceexecution is hardly a discrepancy. That's a HUGE variance.

Can you make a suggestion on how to fix this? Is this behaving as expected??

Hello calhawk01,
Thanks for your note.

Intrabar granularity and inaccurate fill concerns are present on all platforms in back testing/optimization. Most individuals use back testing/optimization along with walk-forward simulated testing to ensure their strategies are indeed profitable. The main issue is that there is no way to know how exactly an order would be filled by your broker using historical data, as well as computational complexity issues. For example, imagine running an optimization on an hourly chart of 10 variables over three months with thousands of ticks per hour. Most of the design of the strategy analyzer has this in mind, to be the most accurate it can be while not trading off efficiency, and was not unintended.

There are a few options for improving the accuracy to your strategies results:

1. Use a reference sample available in our forums on increasing intra-bar granularity
2. Change your backtest fill algorithm
3. Changing your CalculateOnEachTick setting
4. Do your backtesting using Market Replay.

Using Market Replay for back testing would replay historical market tick data, and its possible to have a strategy running and placing trades during the replay on the Replay101 account.

I am including the relevant help guide documentation and forum links from this post, for your convenience.
