Yes I realize that. I meant I'm still trying to find the layperson reason that the SEC is justifying this with.

Dude there's way more than just penny stocks that trade with penny spreads. I don't see how this would be useful to anyone and I'm still trying to grok their actual argument for doing it.

BTW if I remember correctly this was also the decision making process whereby retail firms were locked out of the decision making process but firms like Citadel were invited to the table. That speaks volumes.

Won't matter to her - she never earned a dime of it.

This is crap nonsense designed to benefit Wall St firms as usual. Lack of liquidity is a result in lack of interest in a rigged market. Kill the fragmentation, severely hamper HFT, outright ban payment for order flow, and return the market to some state of organic behavior and then you'll see...

Right because if election results turned out a different way and GBPUSD dropped 300 ticks then what would they have to say? Don't get me wrong, I also profited (at the time) off the GBPUSD strength last night - but to think any kind of "system" had that nailed is a bit ridiculous. It ripped...

I had a crappy week too man. Just put it behind you.

First off, if I were hellbent on speed I'd simply write it in POSIX C as I do most of the stuff I'm concerned about speed wise. Otherwise I'd write it in Perl. If I wrote it in Python I'd write it the straightforward route first - and then optimize if necessary. Stop being hard headed. You're...

I'd think for any non-native spread you're stuck legging in anyways unless you have an auto-spreader, right? I figure for the exchange spreads it won't make a difference.

WTF? If he uses the built in CSV library or panda libraries he'll have his array-of-arrays output to deal with. We're not dictating the actual lines for that because it's cookie cutter crap that anyone who understands basic languages will know how to deal with. When you talk about trading do...

Yes because the MACD indicator really knows how to predict election results. Sheesh.

The fact that you seriously think all of that has to do with Python cracks me up. I don't even like Python but you're just grinding a pointless axe here.

Is it the formula stuff being done in this video: I realize that's IC but the functionality might be the same.

xandman, is that Qtrader or IC? I've been considering opening an account at DDT with the Qtrader setup to better trade spreads.

volpunter, funny that you're sitting there telling "us" (meaning the people that told the guy to stop writing such ridiculous square-wheel code) that none of us helped him and only tried to upsell him and instead you're here turning this into a Python sucks, C# rules thread. How did you not...

Are you seriously adding the 'join' string rather than using the join *function*? That is not the way to do things.

That just about goes for everything.

Quick everyone buy as much SHAK as they can to mess with Surf ala Icahn/Ackman HLF style.
