Even if it's based off the value chance rather than a percentage change, it's still not working right. My original entry price was $4.33712/$4.40606, with a trailing limit at $2.00. For the trailing limit to now sit at $2.1385 then the Bitcoinica price would have had to hit $4.46/$4.53 or so, and at least looking at the time range it never went anywhere near that high. But now we've had some more movement, so let's re-evaluate.

Currently, my trailing limit stop sell is at $2.2734, an increase of $0.2734 from the original price. Have we come anywhere near $4.50/$4.68 on Bitcoinica during the past day? I guess it's possible, with large movements, but I'll leave my order in to see what happens over the course of yet another day. I'm still pretty sure it's moving every time there's a noticeable change in pricing up, not taking into account the original price.

Edit: Seems to be holding as my limit stop sell is still at $2.2901 after all the recent movements. I'll leave it up more to verify, but it looks like my main error was in assuming it was percentage based rather than absolute values.
So here we are, a few days later, and I've now killed my trailing stop sell. Why? Well, check this out:



You'll note that three days ago when we were in the $4.50 range give or take, my $2 original trailing stop had increased to $2.2734. Here we are a few days later and the maximum price we've had since I started this order is around $5.20. That's an increase of nearly $1 since I created the trailing stop sell, but my trailing stop sell has gone up a whopping $2.2945. The spread would have need to have hit $6.60/$6.70 or so for the trailing strop to have changed that much -- if it were being calculated correctly. I'm not sure how frequently it gets updated, but whatever is happening the code for trailing stops does not appear to be working right.

RandyMarsh, how about your trailing stop buy order at $50 -- what's it at now? I'm guess with the movements we've seen, you're probably down to maybe $48, unless the code is even worse than it appears. Maybe it's down to $40? LOL
