There are ways you can simulate (stimulate?) an uptick using ECNs. On the Nasdaq it is techncially called the Bid Rule. The inside Bid must be equal to or higher than the last trade for an uptick situation to occur. Ergo, if you step up, or make the software step up, with an equal bid no matter how small, you then have an uptick situation. Talk to your software developer ;-) "Soooo, how much software do you want to buy..." Indeed.
Quote from stuckie: trade through arcx...they have no uptick rule Has this changed recently? I trade listed stocks on ArcaEx, and there is, indeed, an uptick rule being enforced.
As I know, ARCA have an implicit uptick rule, you don't see it but it will wait until NBBO is up. I have already seen that in their small print characters.
Don't know about listed, Alan...but you can trade without the uptick on Nas through arcx and isld (now their on CINN). When inca and isld merge, we lose the isld one (they go to Nas). But TT2 is right...your developer has to talk to the ecn and set it up. Stuckie
