It's either a bad tick or your software should have filtered it out.

Hey OP

Here's a link that should clear it up for you - its from the TMX Exchange (Canada)

http://www.m-x.ca/marc_terme_appli_en.php#mta5

It clearly states:

"the block trades shall not set off special terms orders or otherwise affect orders in the regular market."

So in a nutshell - your stops are safe

Interesting to know this. I see a lot of these ridiculous highs and lows a lot for many stocks almost everyday. Like viruses polluting intraday and eod data and deceiving computers and traders. Very annoying.

totally agree. but once again-looks like nobody gives a the shit about it. impossible to do any proper back testing. i did backtest one of my ideas-200K annually. profitable every month.reality-10 times less. at least my own soft and programming knowledge gives me flexibility to filter those unrealistic fills.

most respectable charting programs can filter out those bad ticks.

rogue prints, it happens. your charting software is shite.

I was under the impression that these block trades were mostly done via dark pools so should they not be should be considered OTC and only post to the consolidated tape on a delay? (feel free to correct if I'm way off)

I'm going to be leaving my current job trading cash nat-gas and would like to get back into trading equities. I'd like to make sure I get charting software that filters these ticks.

thx in advance for any advice

I see this happening on my TOS platform every now and then, and when I ask about it via their online chat, the standard response I get is "it's the data service provider."

TOS has a manual correction feature where you can highlight the chart and manually adjust the correct hi/low for the bar.

I'm wondering if Esignal or another charting program has the ability to catch these glitches and reset the chart automatically when it's determined that the print was bogus.
