Halts are based on specific criteria and rules, they aren't arbitrarily imposed.

Well, we might want to consider changing the criteria a little bit. No?
I think that going up or down 10% (or more) in a span of 5 minutes is a pretty solid criteria for automatic halting, which is what it is today. If you have a better proposition for the halting criteria, please post it here.

What do you think of tradytics? Looks really interesting, though I mainly trade OTC, which I sort of doubt it has much support for.

haha I am the developer of it so I can't really say anything lol. Although we don't have OTC, a lot of other stuff is free on the website so give it a go with a free account. Always happy to answer questions.

It looks good, I'll definitely give it a real try if I start trading options more, the order flow data alone looks like it would make it worthwhile. Do you incorporate L2 data? Couldn't find that anywhere, only thing that seems like its missing.
but options expire on friday? why pull off a dump now?
Here are the options flow stats, crazy amount being spent on options. https://i.gyazo.com/dca500ef0f774a0019f0a42b7ac1e855.png
