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 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.

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.

Working for me too on both my machines. Though, yesterday to test it out I took a small long position that I was pretty sure would get zhoutonged. Your helper told me the zhoutong price was around 6.39, but my position held until the low 30s.

I'm using the calculations posted by zhoutong, so I think they're correct. There's a small bug in the code though that may affect the result of calculations a bit - it takes only first two digits from the bid/ask price (it's because in the code they are split up to make the rest of digits gray). On small positions this could show up as a visible difference, and you just saw it. I've fixed that error and pushed a new version. Remember to uninstall the old one, because you can end up with two different versions running at the same time. EDIT: It's not that easy to actually test that. I've created a 10:1 leveraged 9.5 BTC position (having 1 BTC on account) and here's the result: I should've shorted, because I don't think we'll hit 6.2 again

I have a small feature request. I would like to be able to click on the quantity buttons even if I don't have enough money to buy. I want this because: -Sometimes I want to sell using those buttons. -Sometimes I want to buy more BTC after the price goes up. Needing to refresh the page or enter the number manually is rather annoying (when those buttons are already there but just grayed out). I'm using the calculations posted by zhoutong, so I think they're correct
I found your problem. This: // Long if (amount > 0) min_price = Math.round((ask - ((net_value - maintenance)/(amount + btc))) * 100) / 100;
// Short else min_price = Math.round((bid - ((net_value - maintenance)/(amount - btc))) * 100) / 100;
Should be this: // Long if (amount > 0) min_price = Math.round((bid - ((net_value - maintenance)/(amount + btc))) * 100) / 100;
// Short else min_price = Math.round((ask - ((net_value - maintenance)/(amount - btc))) * 100) / 100;
(Notice the change to "bid" and "ask"). It seems to fix it. To test it to see if it was accurate, I changed it like this: // Long if (amount > 0) min_price = (bid - ((net_value - maintenance)/(amount + btc));
// Short else min_price = (ask - ((net_value - maintenance)/(amount - btc));
(Notice the removal of "Math.round"). This allowed me to have it display all of the digits it uses. I tested it for a 10:1 account: -Manually doing the calculation resulted in 6.665561463414634146341463414635 -Using the test script resulted in 6.665561463414635 So it's accurate to 15 digits. (By accurate, I mean it yields the same result as doing it manually). Now that it works correctly, I wanted it to show 4 digits instead of 2, so I changed it like this. // Long if (amount > 0) min_price = Math.round((bid - ((net_value - maintenance)/(amount + btc))) * 10000) / 10000;
// Short else min_price = Math.round((ask - ((net_value - maintenance)/(amount - btc))) * 10000) / 10000;
(Notice the change from "100" to "10000"). With this change, it will now display the correct minimum price to 4 digits. PS: Thank you for making this script.

I found another bug.
Sometimes, the BTC/USD prices are updated separately from the panel on the right. When this happens, the "net value" is based upon a BTC/USD price that was updated at a different time. This means that the "Min price" will be changed. The "Min price" should never change.
It actually had a significant effect on the "Min price" today, due to the volatility. At one point, the value was inaccurate off by over 0.10 BTC/USD.
I'm not sure how this could be fixed.

Done. Version 1.2.0 is completely safe, as of this message. @M4v3R: You can get rid of line 12-20. Mootools makes unsafeWindow obsolete. I'm glad to see that you moved away from unsafeWindow, though.

@Maged: Yeah, the code for unsafeWindow is obsolete now. I've also changed "addMootools" function to just "addScript", because it wasn't loading Mootools (I wanted to do that in the first place, but I've changed my mind), just adding the script to main page body. Thanks for the suggestion.
