NinjaTrader 7 and 8 check that you're authorized to run certain indicators, including BCT indicators. It uses what's called your Machine ID to check that you're an authorized user. If your Machine ID isn't recognized as able to run an indicator, you'll see a message similar to the following:
If this occurs, you may be able to easily resolve this on your own without waiting for support or creating a support ticket.
What you can do is assure that your newest Machine ID is properly registered for your account. You can do this using the BCT Indicators download page.
On the BCT Indicators Download page, select the indicator you want to download, then paste your Machine ID into the box below "Ninja Trader Bundle Download", which contains the words, Machine ID. Paste your own Machine ID into that box. (See the info below if you need assistance in locating your Machine ID.)
Once the Machine ID has been entered into the required box, hit the Authenticate Indicators button to the right and your Machine ID will be linked to that indicator.
More Detailed Additional Instructions
These steps should appear similar to what's shown in the image that follows this paragraph. Note that if you do this for more than one indicator, make sure you hit the RELOAD button above the pulldown before selecting a new indicator from the pulldown. Again, copying and pasting your machine ID is recommended, as it's easy to make an error if typing it in manually.
To get your Machine ID from either NT7 or NT8, open the Help/About menu. That brings up a dialog that includes your Machine ID. Locate it, and double-click on it, then use CTRL+c to copy it (or double-click to select it and right-click on it to get the Copy menu) so that you have the Machine ID number in your paste buffer.
IMPORTANT: Make sure you copy the correct Machine ID. Do NOT try to use your License ID, as it might allow you to download the indicator from the BCT website, but it won't run without warning about licensing. Your Machine ID will likely only contain numbers and the letters A-F (a hexadecimal number). The Machine ID is highlighted in blue in the following image (notice it's labeled as such to the left of the selected text):
Then go to the BCT downloads page, choose the indicator you want to update your license for, and paste (CTRL+v or right-click/Paste) it into the box that is requesting your Ninja Trader machine ID. Then click the Authenticate Indicators button. This will connect the new Machine ID to your account, and you should be able to run the indicator. Note that you do not need to download and install the indicator again if you already have it installed. This just assures that your Machine ID is being properly recognized.
If this does not resolve the problem, then please contact support for assistance.
