NOOB: Info on buy/sell order for EOD data

[zwoop]

It do not have to be a double, i have also tried with an int but get the same error. It must be possible to use an int as an array in this way???

[NinjaTrader_JoshP]

If you want to use an int please use an IntSeries. Same exact concept as DataSeries. http://www.ninjatrader-support.com/H...riesClass.html

But i dont want the array to contain any bar data. I just want a simpe array that contains different int values that has nothing to do with the current bar chart. The references you sent me bouth state "that holds a series of int values and ALWAYS contains the same number of elements as bars in a chart". So it is not possible to use standard C# arrays in NT?

My second question is if there is a indicator for historical volatility in NT? Cant find any info in the help files. I did find this old thred

http://www.ninjatrader-support2.com/vb/showthread.php?t=5385&highlight=Historical+Volatility

but there is no one from NT that has comented if the indicator is exact or if it has any errors?

Man this is not my day I have a sterategy that has errors in it but now i want to start making an indicator. However when i am compiling the indicator i get errors from that strategy. Why is that i just want to compile the indicator and i dont want to do anything with the strategy.

zwoop,

All NinjaScript files compile at the same time when you press compile. They all need to be error free. If you don't want to finish working on an unfinished work before starting on a different you can comment out all the uncompilable lines to let it compile and then let you work on your indicators.

If you want a C# array you will then have to use the C# techniques for achieving this. Unfortunately this is outside of what we can cover. I suggest you try searching on google for some resources on how they do it though.

but there is no one from NT that has comented if the indicator is exact or if it has any errors?

The way i have made the array is the standard C# way that is why im puzzled when i get the error

Hello,


I'm jumping in here, so I may be way off, but:

Post your code and we can help.

A good volatility measurement can be found via the Bollinger indicator.

This is my code now, all i want to do i use a simpe array as it is outlined in the code but i just get an error doing so.

zwoop, unfortunately we can't debug those C# methods for you, however you can take a look at this thread here members discussed related topics providing valuable insight into using arrays / arraylists in C# - http://www.ninjatrader-support2.com/...ad.php?t=24801
