HGSI crashes when using the Intraday Option to "Update Intraday Data Every xxx Minutes". See the WARNING under the Thinkorswim section of the Intraday Help Topic.
HGSI crashes when you have an old version of Thinkorswim installed on your computer. Download and reinstall Thinkorswim or if you prefer, you can uninstall and reinstall Thinkorswim. (Note: It doesn't matter if Thinkorswim is providing a message saying you have the latest updates. There is a component of Thinkorswim that only gets changed if you do the reinstall)
You receive the error message:
"Thinkorswin doesn't appear to be installed. You
must have the Thinkorswim desktop application installed and running
to retrieve intraday quotes with this provider"
Action to take: Download and reinstall TOS. (Note: It
doesn’t matter if TOS is saying you have the latest updates. There
is a component of TOS that only gets changed if you do the reinstall).
Or if you prefer, you can do an uninstall and reinstall of TOS.
