161  Economy / Trading Discussion / Re: When Mt. Gox was at $17.95, TradeHill was at $16.90 on: July 02, 2011, 07:19:12 PM
OP is on crack.

TH BTC/USD prices are consistently higher than gox.

Anyone can verify this by just taking a look at both exchanges at random points during the day.

Nothing wrong with crack, but do be careful when driving.
162  Economy / Trading Discussion / Gox trade orders not exeucting? on: July 02, 2011, 06:28:09 PM
Last 30 minutes:

Log into gox
Check market data (depth)
Note bid prices
Enter Sell order 0.01 below bid price
... wait 10 minutes ...
nothing (bid and ask unchanged in market data)

Check market data again
Enter Sell order exactly at bid price
... wait 10 minutes ...
nothing (bid and ask unchanged in market data)

I continue to switch between the above two, no change.  My orders aren't getting executed even though they are clearly in my queue.

Huh

Indeed, seems like cablesaurus has abetter deal.  Their cable is 19cm (~ 7inches) and costs far less.  Oh well.

I will say that the Amerirack cables are quite tough though. 

$100 for a 12" cable? I'm seeing that right, right?

If your central AC is cooling your house in order to compensate for the sun heating it up (and hence cooling your rig in the basement nicely) remember that it won't feel the need to cool as much at night (since your upstairs is cooler due to lack of sunlight).

EG.,  my basement temps rise about 2-3 degrees overnight.

I've used these.  Prompt shipment and a quality product (unlike some others I've tried, like Ameri-Rack).

They come in different lengths too iirc.

I can see prices on bitcoincharts and bitcoincity, but my browser spins endlessly waiting for mtgox.com.

;-(

It's back now....

Painfully slow.

I don't see how a ferret on meth could click ONLY three times a day.  I have this image of a crazed animal clicking incessantly several thousand times a day (despite the lack of a button to click).

That's what I do to check my hashrate.  ;-) 

Thankfully, I'm not a fan of meth personally.

Oh well.  It's not that bad to have to click "pay me now" a couple of times per day.

Like a ferret on meth.

Several posts on the gox forum (on gox itself) about this.  You're not the only one afaik.

You're not being a jerk at all.  This was a totally hypothetical question anyhow.  If I had really (strongly) thought that it would have worked, I wouldn't have posted about it.  ;-)

Really not trying to be a jerk, but just think about it a little longer and you'll see exactly why this won't work.  You can only move the Bids ***OR*** Asks, not both.

I wasn't aware than automatic payment was only once every 24hrs.  Seems odd to have an automatic payout minimum setting (eg., value param) that's based more on time, which is a param we can't set in the interface.

Oh well.  It's not that bad to have to click "pay me now" a couple of times per day.

Did you definitely wait 24h after your last manual payment?
172  Economy / Trading Discussion / Re: What's to stop the following type of market manipulation (example using TH)? on: June 29, 2011, 11:12:11 PM
Therein lies the rub (and the gambit).  I'll have to try some tests.

In the meantime, I'll go back to step 1:  collect underpants.

;-)

When the price is above its medium-term average, people are anxious to sell. They know they're getting a probable windfall. So it takes a lot of shares to push the price up. The net effect is that in the very short term, the further the price is from the medium-term average, the more it wants to go back to the middle and the harder it is to keep pushing it. Sell orders will keep flooding in and buy orders will not. So the part you are paying for is "uphill" and the part you are getting paid for is "downhill".

173  Economy / Trading Discussion / Re: Trading 101 on: June 29, 2011, 10:43:10 PM
I challenge you to create a strategy using what you suggest below and implement (eg., backtest) it on any major stock market index.  

You might find it harder than you think to make those simple rules work (eg., be correct more often than not).

You must understand that these limit buy/sell orders on the exchanges do not mean a lot. It's merely protection from big price fluctuations. They can (will) be deleted when any news arrive. They only good indication for price direction is volume.

If price goes up and volume increase - strong buy signal.
If price goes up and volume decrease - sell signal.

If price goes down and volume increase - strong sell signal.
If price goes down and volume decrease - buy signal.

Hope it helps someone...

The price went down because that was their intent.  They drove the price in the other direction.

Basically, the massive selloff lends credence to what I'm saying, just in the other direction.  So you could implement that strategy, then buy up a TON of bitcoins when the price has been driven down so far ... then wait for it to come back up.

assuming you bought enough btc to move the market (which would take a LOT of cash) there is no guarantee you can sell them at the ask price. in fact selling all those coins at once would crash the price of the stocks you were trying to sell (killing your profit) unless you were selling dark pool.

in fact, a massive selloff (like you propose) crashed mtgox and drove the price to .01
175  Economy / Trading Discussion / Re: What's to stop the following type of market manipulation (example using TH)? on: June 29, 2011, 10:35:33 PM
I'd like to say first that "fair market value" is whatever the market says it is.

So I sell my shares at $18.75 (your example below) then and follow the price back down to $17.

It's not a crazy assumption to suggest that "on my way up to $20" I've actually paid on average about $18.5 for those shares.  So I've got about 5k shares at $18.5 and another 2k at $17.

If I sell them all at $18.5 I'm still very much in the green.

No, no profit.

3) Other people see that the price is above market value and they decide to take advantage of the opportunity your waste of $100,000 has bought them. They put their shares in at $19.00. These orders still don't complete because that's still too high. But a few more people decide to take advantage of the opportuntity to sell at $18.75. The price starts dropping fast and your sell orders never completed. Soon, the price is back to fair market value. You're left with a bunch of bitcoins you overpaid for.

176  Economy / Trading Discussion / Re: What's to stop the following type of market manipulation (example using TH)? on: June 29, 2011, 10:18:01 PM
To get around that, couldn't I just follow with my own bid orders closely following my ask / buy orders.  That would keep the bid/ask intersection close to where I'm buying.

Plus, as I buy, I'd be increasing the highest bid order.  I suspect others would trail behind.  No?


Let's say I go on Tradehill right now and buy up all the ask orders up to $20 (about 5.5k btc).  That would in effect raise the price to $20 on that exchange, assuming my orders get fired off in a timely fashion.  

[Insert:  I think I'm missing something here about my ability to make the price go up to $20 in the above step ... but I don't see where.]

You are.  You haven't distinguished between "ask" and "bid" prices.

Your buy up of ask orders does nothing to the bid orders.  They would remain at the lower price, so when you come to sell, you would make a huge loss.
177  Bitcoin / Mining software (miners) / How to create a distributed GPU network like bitcoin for number crunching? on: June 29, 2011, 10:15:03 PM
I have a bunch of algorithms I'd like to run, testing various parameters, using something like the distributed model of bitcoins (without hashing or security) so that when I'm not mining, I can use the HP of my rig to crunch numbers.

Any good pointers on how to get started on something like this?  What I'm mainly looking for is two things:

1.  How to interface with OpenCL (which I can likely get from AMD).

2.  How to make it a distributed model where a central server says something like the following:

   return_data[tag] = run_on_network_cluster(my_function(), param1, param2, param3, param4, ...);

So that I can collate all the data in the end and sort it at the end.  EG., each run will have a unique output.

Ok, so just one thing.  ;-)

Thanks.

Just thinking out loud here.  

*** The following assumes I have 2k or more of btc already purchased at around $17 ea.

Let's say I go on Tradehill right now and buy up all the ask orders up to $20 (about 5.5k btc).  That would in effect raise the price to $20 on that exchange, assuming my orders get fired off in a timely fashion.  

[Insert:  I think I'm missing something here about my ability to make the price go up to $20 in the above step ... but I don't see where.]

Once I've done that (bought all shares up to $20) I then put a massive sell order (for all my shares ~ 7.5k btc) in at just below $20 (eg., $19.5) which includes the 2k of coins from *** above.

Seems like guaranteed profit to me.  

I'm always wary of guaranteed profit so thought I'd check here.

PS.  If you implement the above and make a fortune, please donate to me at 1ANHjo35p88GanFoe1Rawb5straQpE8Sfq

Has automatic payment been broken for a while?  I have mine set to 1.0 btc and have had to manually initiate payouts for the last several days (all of them higher than 1.0 getting as high as 2.0).

Wallet hasn't changed.  Nothing has changed except my adding new workers.

Thanks,

Getting the infamous "MySQL error, please retry later" message again.

Right in the middle of the trading day.  Ugh.
