Plot Reset

[bukkan]

I have this 2 lines of codes in onbarupdate.

Plot0.Reset();
Print("Plot0: " + Plot0[0].ToString() + " Close:" + Close[0].ToString());

now the Print comes out as

Plot0: 5639.05 Close:5639.05
Plot0: 5638.7 Close:5638.7
Plot0: 5638.7 Close:5638.7
Plot0: 5641.85 Close:5641.85
Plot0: 5643 Close:5643
Plot0: 5644.4 Close:5644.4
Plot0: 5645.85 Close:5645.85
Plot0: 5641.25 Close:5641.25
Plot0: 5635.15 Close:5635.15
Plot0: 5635.6 Close:5635.6
Plot0: 5640.15 Close:5640.15

pardon me if i sound too foolish but Reset is supposed to be null values, right. But it is printing out the close of the corresponding bar. am i missing something.

thanks in advance.

bukkan, I will have someone get back to you on Monday.

I think you need to use ContainsValue() check. Dont assume Reset stores null (it probably cant due to data type implementation). See Josh's example here http://www.ninjatrader.com/support/f...ad.php?t=33061

if i am not wrong but if one call the dataseries from a strategy then ContainsValue is not an option.

bukkan,

DaveE is on the right track. Basically, the DataSeries holds a placeholder value and that value is the Close[0] price so that is why you are seeing identical prints. It would probably be easier to see the .Reset() effect if you had the DataSeries set to values other than close to begin with for testing purposes.

As far as testing ContainsValue, you can and should do this in the strategy. For example:

SMA(20).Value.ContainsValue(0);
MACD(12, 9, 26).Avg.ContainsValue(0);

thanks for the clarification Josh and thanks to DaveE too.
