DrawText Slope

[stockgoblin]

Hi,

I've been able to adapt another indicator

[NinjaTrader_Lance]

While this would not be very efficient and could put a strain on the system to check all the previous bars every new bar you could do so using a for loop.

Specifically a foreach loop if you need to check ALL previous bars: http://msdn.microsoft.com/en-us/libr.../ttw7t8t6.aspx

Additionally I don't know how much you've looked into calculating slopes but this may be of use: http://www.bigmiketrading.com/wiki/t...-in-indicators

Hi

Thanks for the info.

This depends on what you're looking to do with this data. Are you going to draw something on the chart or do you want to store this for later reference?

[stockgoblin]

Yes, I'd like to Identify

[NinjaTrader_Lance]

In this case you could just draw the object when it occurs. When you load the indicator onto the chart it would start at bar 0 and progress over the historical data drawing the objects along the way.

Using your example, something like

if(Close[0]-Close[1] == Close[1]-Close[2]) 
//draw line

might work.

However if you needed to check more than just the previous two values you would need to create a loop.

Yes, I do need to check

Those C# reference links will be a good place to start. Additionally I often find this website to be more educational for newer users: http://www.dotnetperls.com/for

Additionally we have recently begun offering premium education courses for learning NinjaScript: http://www.ninjatrader.com/PremiumEducation.php

Let me know if I can be of further assistance.

Hey, that's great. I'll check that out.

Hello,

While you wouldn't have to it would probably be easier to use a DataSeries to store the slope values. You could then loop through that series using the for loop.

In terms of resources the time frame isn't going to be as important as the total number of bars loaded on the chart. The more bars, the more data it will have to loop over.

[stockgoblin]

Wow,

Thanks for that link. The SampleCustomDataSeries.zip indicator is exactly what I need to learn from and experiment with adapting them and building on them. Are there more of these Sample indicators in one place?

[NinjaTrader_Lance]

Yeah no problem. All of our samples and tips can be found on the main page of our forums.

Nice, I got it!

Your NinjaScript / C# Code will always be logically processed and evaluate according to your set logic – this can of course lead to unexpected results at times, thus we would suggest to simplify and debug your code to better understand the event sequence it would go through - unfortunately we cannot offer such debug or code modification services here, but please see the provided resources below to help you proceed productively :

First of all you would want to use Print() statements to verify values are what you expect. Its my assumption that the script my have an error if you were to open up the output window (tools -> output window) - Debugging your NinjaScript code.

For strategies add TraceOrders = true to your Initialize() method and you can then view valuable output related to strategy submitted orders through Tools > Output window - TraceOrders

It may also help to add drawing objects to your chart for signal and condition confirmation - Drawing Objects.

If you would prefer the debug assist of a professional NinjaScript consultant, please send mail to support [at] ninjatrader [com]
