Bitcoinica and the 0.0123 bot

[phantomcircuit]

I believe I have an explanation for the 0.0123 trades, in short they appear to tighten the spread on bitcoinica.  As we all know his algorithm has some measure of volatility, so presumably this would also apply in the opposite direction.

I dont see what youre talking about.

Why so jelly?

Me neither... but on a side note, i've noticed a lot of > 0.01 BTC trades placed. The only explanation I can think of is bots testing for market movements? Why bother otherwise? I think its trades like that in huge numbers which really slow broker trading engines down.

phantomcircuit youd better give an explanation or you just made yourself look incredibly unprofessional. a quick view in a couple of recent threads and one gets the impression that you feel jealous.

Code:

<chsados> phantomcircuit my theory is that bot manipulating the price of mtgox/bitcoinicas instant buy buttons
<chsados> hoping to get mtgox buyers who dont check the order book 
<phantomcircuit> chsados, my theory as well
<chsados> i also thing the bot is putting in medium sized buy orders when theres not much activity to jump the price up to move it closer to its large sell wall

Is that like somebodys way of scalping for profits? I'm pretty sure you could counter that bot and make a killing from it by understanding how it works.
