Hello benrock,
Thanks for your post and I am happy to assist you.

You can code a 3 bar uptrend/downtrend within the strategy itself. A basic code would look like

if (CurrentBar < 3) return;
if (Close[0] > Close[1] && Close[1] > Close[2] && Close[2] > Close[3])
{
	//do something
}

You can easily create the basic framework using the Strategy Wizard.

Also please see this YouTube video tutorial on the Strategy Wizard.

You can also consult our NinjaScript consultants to create it for you. You can get the list of our NinjaScript consultants from here http://www.ninjatrader.com/partners#...pt-Consultants

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

Hello benrock,
The basic configuration via the strategy will be like as shown in the attached picture.

Please note after you have coded the strategy you have to unlock the strategy and add the below code just below OnBarUpdate.

protected override void OnBarUpdate()
{
	if (CurrentBar < 3) return;
        //rest of the codes

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

Hello benrock,
Since you are referencing to 3 bars back, you have to make sure there are enough bars in the data series you are accessing. Please read this post for further describes it http://ninjatrader.com/support/forum...ead.php?t=3170

Unfortunately you cannot check the bars back via the Strategy Wizard. You have to unlock the Wizard (click the Unlock button in the wizard as shown in the attached picture) and append the below code via the NinjaScript editor manually in order to do so.

protected override void OnBarUpdate()
{
	[B]if (CurrentBar < 3) return;[/B][COLOR="Green"] // add this line to your code manually[/COLOR]
        //rest of the codes

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

what do i put for user defined inputs ?

[NinjaTrader_Joydeep]

Hello benrock,
Since in this case you do not have any user defined input please leave it blank.
Please let me know if I can assist you any further.

Hello benrock,
Once you have unlocked the code please make sure you have compiled it.

• In Control Center menu bar goto Tools>Edit NinjaScript>Strategies
• In the Strategies dialog select MyCustomStrategy and click on the Ok button.
• In the NinjaScript Editor press F5 to compile it.

Also to understand the issue better, can you share a screenshot showing the issue?

To send a screenshot press Alt + PRINT SCREEN to take a screen shot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

Hello benrock,
The code I presented only filters the conditions. You need to further code it (via the wizard or the NinjaScript editor) as per your requirement. Please let me know if you have any specific query.

If you are new to creating strategies then please go through this YouTube video which demonstrates how to create strategies via the Strategy Wizard.

Also please go through the educational resources from our help files http://www.ninjatrader.com/support/h...strategies.htm
