EDIT: Bid 4.96494, Ask 4.96495. What the actual fuck? Have never seen spreads this low! Is the manipulator trying to kill those betting on vola?

From the mtgox api. Those 0.01 sure look solid to me.

Stationary prices bore me. A meteor crash or secret rocket would cheer me up.

Oops, meant to say volume.

It seems as if the price repeatedly attacks the ~4.927 support. If it breaks, we could be in for a meteor impact.

I'm starting to feel desperation now. Where is the volatility? Where is the liquidity?

(x) I do not understand options, and use them in my trading strategy 

I'm at the "I'm brilliant" stage. But I just started trading (again) yesterday so I suppose I haven't synched with the board feelings yet.

1. Turn starts
2. Alice puts a buy order at 5 USD for 10 stocks
3. Bob puts a sell order at 6 USD for 15 stocks.
4. Charlie puts a buy order at 6.5 USD for 5 stocks.
5. Danny puts a buy order at 6 USD for 5 stocks.
6. Eve puts a sell order at 5.5 USD for 5 stocks.
7. Turn ends, order matching begins.
The system now finds the price at which the most orders would be executed. If there is a whole interval in which the most orders would be executed, the midpoint of said interval is selected.

At 5    USD there is demand to buy 10+5+5 stocks and to sell 0 stocks.
At 5.5 USD there is demand to buy 5+5 stocks and to sell 5 stocks.
At 6    USD there is demand to buy 5+5 stocks and to sell 15+5 stocks.
At 6.5 USD there is demand to buy 5 stocks and to sell 15+5 stocks.

The point with maximum volume is 6 USD.

People with eligible orders are
Bob, Charlie, Danny and Eve. Since Charlie put a higher price in his buy order, his order is given preference over Danny's. Since Eve put a lower price in her sell order, her order is given preference over Bob's.
Ties would have been resolved randomly
Therefore Eve gets to sell 5 stocks (completely filled), Bob gets to sell 5 stocks (partial fill), Charlie gets to buy 5 stocks (completely filled) and Danny gets to buy 5 stocks (completely filled). All this at price 6 USD/stock.

8. Orderbook and made trades are made public.
9. Turn starts.

Nothing says only one order can be executed per turn.

What is it that they want?

The way the stock markets currently works, having your trading bot in the same room as the exchange is vital. Every millisecond counts.
I would argue that the pursuit of these milliseconds are very uneconomical. Sure, providing oft updated reports on where people think the future is head IS important, but I think the resources used do not match the utility produced. The reason then, is that people play a cynical zero-sum game.

I therefore think it would be prudent to try to prevent this from occurring, letting traders instead compete on intelligent algorithms and models.
An often suggested solution is the Tobin Tax. However, given the rates often quoted, I think it would also prevent "healthy" speculation: the kind that ensures the efficient allocation of capitals to various projects.
I have an alternate suggestion: turn based trading
It is a really simple system. People can place their orders anytime they want, but orders are only matched once per turn. Also, orders are only revealed when a turn is over. The length of a turn is on the order of seconds.
This means that no one can take advantage of being closer to the servers by getting their orders in before someone else. Also, it would be impossible to try to glean other traders' strategies and outbid/frontrun them before they even see it happening.

Some people say that it doesn't matter that coins get lost due to divisibility. But assume that an evil hoarder keeps his gold so long that all presume it to be lost. Said person could then, when showing everyone the true amount of availible bitcoins, cause a great the deal of instability.

The chain just uploaded a promo where they demo buying a burger with Bitcoin!

Omg, this is huge

I would want an audit to check that the website is hard to hack:

• hashed and salted passwords
• updated software
• input sanitization
• balances on a separate box from website

I would also welcome info about who to sue when shit hits the fan.

Sometimes, I feel more lazy than I feel paranoid. Would it be possible to give you api access to withdraw/deposit, so that I would not have to pay invoice manually?

This is awesome! Thank you so much for making this happen.
