what exchange is "H"

I am looking at ameritrade time and sales, exchange codes "H" .... I don't know what this is.

and it doesn't say in their file:

The link you provided claims it is "ISE Gemini". Did you buy an option?

 

no it is for stocks

 

Yep, I too see it providing stock quotes at TD. 'H'ucksters would be my guess.

 

It may be MIAX - Miami International Securities Exchange.

At least one of our sources in MT codes it as "H".
