This may not work but there are 4 combinations of ways to link to a brokerage or charting program. In the Set Up External Linking window, you will see that there are 2 boxes: 1. Beginning is cut off and 2. Alternate Method.
1. Generally to establish a link, you don't have to check those boxes, you just drag the crosshairs to your program and the link is done.
2. Check Beginning is cut off and then drag the crosshairs
3. Check Alternate method and then drag the crosshairs
4. Check them both and then drag the crosshairs.
There are many charting programs out there - sometimes it's just a matter of trying the various combinations to see if you can establish a link.
