I've made a small userscript that enhances my Bitcoinica experience, I thought that I could share it with others. I already covered it in a other topic, but now that I've added more functionality to it, I think it deserves it's own topic.

What it does:

- Adds the "zhoutonging price" (lowest price your position can handle before it gets liquidated) directly to the UI:



- Adds exchange value to your BTC and USD values when you hover your mouse over these:



- Enables all quick pick buttons, regardless of your balance. This is for quick picking a value to partly liquidate your position.

How to get it:

The script currently works in Firefox and Google Chrome.

Download this userscript: http://dl.dropbox.com/u/1127246/bitcoinica.user.js (current version: 1.2.2)
- Firefox: When you click on the link, a popup will appear. Wait for "Install" button to activate and click on it. Note: if the popup doesn't appear, it means you don't have Greasemonkey extension installed. You need to install it first to use this script.
- Google Chrome: Drag it onto your browser's window, then accept the installation.
Refresh Bitcoinica tab if necessary.

Happy trading!

Any way to get this working on Firefox 3.6.25 ?  =]

EDIT: Download and install https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/ and then right click the link and click "View User Script Source", a bar at the top of the next tab/window should give the option to install it into Greasemonkey Cheesy

EDIT2:  Script installed, but doesn't seem to change the layout on Bitcoinica for me at all :/

Is the limit order working as it's supposed to? Right now the sell price on bitcoinica is around 6.60, and if I place a limit order to sell with 0.40 in the add/substract box, I'd expect to see a sell order for 7 USD, but actually it places an order to sell at 6.2...

edit: it works as I'd expect it to if you input a negative value. Useful, but potentially dangerous IMO, since it seems counterintuitive to me. Still, very nice script, thanks!

It's intuitive to me. This feature is designed for price protection, so if you enter 0.4, it means you can tolerate max slippage of 0.4. Then you'd sell at 6.2 as limit order.

any plans to port to firefox?
Change line 14 from:
window.unsafeWindow || (
to:
unsafeWindow.jQuery || (

That appears to work on both browsers, so it should be patched into the main distribution of this.

That's exactly what I've meant.

Thanks for this! I've applied the patch to my script and updated the first post.

OK. I guess I think about it differently. I use limit orders to catch price fluctuations, to sell higher than the current price or to buy lower, and stops to trigger sells or buys if the price goes beyond a given point. That's where my confusion came from. Either way, as long as it's clear how it works, it's a good tool.

As I've said, that's my first take on Greasemonkey scripts. I have some issues with function scope, I'll try to deal with them later.

Correction... a previous version worked... Before I upgraded I just had the min price, but now that's gone too.  Chromium on Linux 64.

Ok, I think I've fixed the problem. Everyone please uninstall the extension first and then install it again (link remains unchanged). Should work now.
