there was one dip that could be used, I've bought some as low as below 123. And it immediately bounced to 133 for minute or two.
On mTGox yes ... not on BitStamp
QED ... you had a 2 minute window
EDIT : I think there were 2 two minute windows today ! 2 minutes might even be stretching it a bit ! Well done if you caught either of them. Me ... I did nothing.
Missed much better window yesterday but caught this one, though not with volume I wish I did.
Best I've done today is just now sold for 129 when I bought for 127...nothing special at all.
Well atleast you did something in order to keep the fees down on Bitstamp. I sometimes do <2% profit trades just to keep the fees under .4%
Large sums of money + low fees can make it all worthwhile.
