If the math in Bitcoinica Helper is correct, the liquidation price is 4.4913.

bid - ((net_value - maintenance)/(amount + btc)) =
4.75225 - ((475.07 - 189.18)/(982.21337 + 113.21337))

Gentlemen, I have done everything with great focus and intent.

All I can ask is that you continue to act within your own nature.

The Communists say, equal labour entitles man to equal enjoyment. No, equal labour does not entitle you to it, but equal enjoyment alone entitles you to equal enjoyment. Enjoy, then you are entitled to enjoyment. But, if you have laboured and let the enjoyment be taken from you, then – ‘it serves you right.’ If you take the enjoyment, it is your right.

My guess is that Jon is shorted with high leverage to around 4.20 and is just goading people to attack his fake bull position.

The bid curve is so flat immediately down-side of the monster wall that I don't see how anyone can take this as a genuinely bullish state of affairs.

notice that after the 5.00$ ask, its even more flat

the monster wall pushed us up 10cents and now look at the bids above 4.6

its looking bullish to me, with or with out this wall

also seeing the ask side grow and shrink grow and shrink all day long tells me it wouldn't take much to make these walls get scared

10:1 long is Crazy ya, but maybe not Totally uncalled for

This Thread is exactly the kind of crap the new forum rules are against.

First they ignore you, then they laugh at you, then they keep laughing, then they start choking on their laughter, and then they go and catch their breath. Then they start laughing even more.

Exactly.  Troll SubForum 2012 - Lets Quarantine this Crap!

On an unrelated note, how awesome would it be if Atlas was actually Satoshi Nakamoto, and that is why he has all these Bitcoins... /conspiracy

The thread was a good idea to discuss leverage when it was made, but I guess I should not have underestimated Atlas’s stupidity. Now it turned into a contrarian indicator.

My guess is that Jon is shorted with high leverage to around 4.20 and is just goading people to attack his fake bull position.

The bid curve is so flat immediately down-side of the monster wall that I don't see how anyone can take this as a genuinely bullish state of affairs.

You really believe in Atlas’s sanity? I’m pretty sure he doesn’t have the ability to be sarcastic or use reverse psychology. He believes what he just said. He also is probably fully aware of what he is doing when he posts such a position.

His long looks too small to me for anyone to bother stop hunting though. If he shopped it, wouldn’t he make it so much that it was worthwhile?

Well, those 1337's sure make it look shopped. I really don't know with Atlas anymore...

4.75225 - ((475.07 - 189.18)/(982.21337 + 113.21337))

each amount needs to be converted to USD at the base price or the bid/ask price.

The bitcoinica helper shows the liquidation price based on the current BTC/USD price  (bid, ask, weighted?, I'm not sure) - however, it's not a constant as it doesn't project falling BTC value in the Currency account (which means a falling margin balance) 

In practical usage, the liquidation price on a long position will rise as the bid continues to fall according to the amount of BTC vs USD in the currency account, accentuating the drawdown dramatically.

The formula above is for a long position, and it is constant.  When I first saw the formula, I also thought it would change with the BTC price.  But it is constant since the net_value changes proportionally with the bid price.

The units/dimensions (BTC vs USD) are also consistent.  The bid has dimension (USD / BTC) and so does the quantity ((net_value - maintenance)/(amount + btc)), therefore it can be subtracted from the bid.  Thus the liquidation price is also of dimension (USD / BTC).

LOL. I use 10:1 for safety during volatility.

A couple weeks ago, when bitcoinica had a software error, and liquidated tons of positions, I was saved by the higher margin level. I would have seen my position force liquidated at lower levels. Instead of being liquidated I made money Smiley

It seems that many people around here risk far too much on any one position. I am much more tolerant of risk in bitcoin than I am in other trading, but still I won't risk much more than 10% of my equity on a position. (I hit about 12% on the error mentioned above) This gives me a lot of room before I go into severe drawdown.

Going "all in" at any level of leverage is just asking for it. Personally, I highly recommend partially hedging your position with your currency account. Drawdown is highly accentuated if your margin is based on a volatile asset in your account, like bitcoin.

I do it this way as well.  I might have 10:1 but I am only using 10% of my account on Bitcoinica.  If someone uses all their capital no matter what their leverage is going to get called.

Introducing constraints to the economy only serves to limit what can be economical.

The formula above is for a long position, and it is constant.  When I first saw the formula, I also thought it would change with the BTC price.  But it is constant since the net_value changes proportionally with the bid price.

The units/dimensions (BTC vs USD) are also consistent.  The bid has dimension (USD / BTC) and so does the quantity ((net_value - maintenance)/(amount + btc)), therefore it can be subtracted from the bid.  Thus the liquidation price is also of dimension (USD / BTC).

Hmm. then this means I am overestimating my risk. Grin I'm ok with that. (I'm sorry to have mislead people though)

EDIT: K. so my original spreadsheet seems to agree with what my brain sees on the bitcoinica page (so now I'm confused)

-the Margin balance fluctuates with what appears to the the "Bitcoinica BTC sell" price (the exchange price, approx but outside the bid price) and is recorded in USD
-the Tradable balance is based on the above(?) and is also accounted in USD

When I run the bitcoinica helper script, my liquidation price changes with the change in BTC price. (as I have USD and BTC in the currency account) - My free margin stopped fluctuating so wildly when I put some more USD to back the BTC in the currency account.

Am I really just overestimating risk?
