Pivot Indicator

[alabell]

Am trying to create a very simple pivot strategy.

Can't seem to get all of the day bars I need loaded so as to begin.

Any advice?

Ty,

Andrew

Hi Andrew,
Sorry, not sure. Is there an error message you're getting? What are you doing to "get all of the day bars"?

[alabell]

the strat compiles fine; it will not work in a backtesting situation, althought I am not sure why;

**NT** Failed to call method 'Initialize' for strategy 'BasicPivot/75a489a2cf07402db56bc4445c3e6458': Object reference not set to an instance of an object.

OK -- what code are you using when you get this error message?

[alabell]

Add(Pivots(NinjaTrader.Data.PivotRange.Daily, NinjaTrader.Data.HLCCalculationMode.CalcFromIntrad ayData, 0, 0, 0, 20));

//Returns PP value
double pivotPoint = Pivots(PivotRange.Daily, HLCCalculationMode.DailyBars, 0, 0, 0, 20).PP[0];

//Returns R1 value
double resistance1 = Pivots(PivotRange.Daily, HLCCalculationMode.DailyBars, 0, 0, 0, 20).R1[0];


//Returns S1 value
double support1 = Pivots(PivotRange.Daily, HLCCalculationMode.DailyBars, 0, 0, 0, 20).S1[0];

Thanks. Initialize() is not used for accessing indicator values, those belong in OnBarUpdate() instead.

You can see here for what Initialize() is typically used for:

much better and we are working now but when i backtest my strat all pivot values still print as zero...any quick fix or am i in deep at this point?

[NinjaTrader_RyanM1]

The main thing to check here is that your calculation mode is set properly for the interval you're viewing. This may seem counter intuitive, but it's:

intraday charts - > use mode daily.
daily chart - > use mode weekly.
weekly charts - > use mode monthly.

I get what you are saying and i think that we are close here, but i think what i need is a bit more specific direction:

---my pivots need to use data from prior day so that they apply today

---my closes need to be "minute, or "tick" based


I am not a coder but know just enough to be dangerous....

how do i set this so that i can see today's pivot points...if i can do this, i can certainly add this result to my otherwise flushed out strategy.

Keep in mind that for now, this is a backtesting exercise.

Thanks in advance,

Andrew

just wanted to get a bit of clarity on ryanm's last post.

I am sure that any of the NT forum moderators should be able to clarify the response.

thanks in advance.

Could really use help so i can do soem work this weekend.

Assuming I am using intraday charts, where do i set the day bars, in the code or in the backtest GUI? right now I have no day bars or minute bars added in the code, because i dont't see where i would reference them in the pivot point function.

Thanks kindly.

Hello Andrew,
Thanks for your note and I am replying for Ryan.

You have to set what type of data/mode etc you will be using from the code itself.

Suppose you are backtesting on a 5 minute bar then the pivot code will be like

double pivotPoint = Pivots(PivotRange.Daily, HLCCalculationMode.DailyBars, 0, 0, 0, 20).PP[0];

if you want the pivots to be calculated from intraday bars then you will have to use the code as

double pivotPoint = Pivots(PivotRange.Daily, [B]HLCCalculationMode.CalcFromIntradayData[/B], 0, 0, 0, 20).PP[0];

Please let me know if I can assist you any further.

[alabell]

that seems very helpful, so if i wanted to backtest the price of a stock every one minute bar against the pivot points for that day, I would use first example correct?

[NinjaTrader_Joydeep]

Hello Andrew,
Yes, you will have to use the first code.

Please let me know if I can assist you any further.

[alabell]

So I have one more question before we hit the the weekend and i am left to fend for myself:


why would this code, when backtested for calendar year 2012 (from jan through july) yield only trades from the last 3-4 trading days?

Thanks in advance,

Andrew
