Just thinking guys, can mtgox be profiting from these tiny trades? Mtgox makes commission on trades, so can they have a bot installed that tries and pushes these small trades?
If I owned mt gox, I would definietly be trying to make a bot do lots of small trades when it can to try and make extra comissions.
let's just do a reality check...
1$ trade means this fee:
1$ * 0.65% = 0.0065$
If I do 2 trades for half a dollar each, I traded a full dollar:
1$ = 0.5$ + 0.5$
and paid the same fee on both half's:
0.5$ * 0.65% = 0.00325$
which results in exactly the same total fee:
0.00325$ + 0.00325$ = 0.0065$
So no, you wouldn't do lots of small trades for that reason.
