what I meant by "losing" money is that the last trade was (say) 8.46 and this bot executes a market order which trades at 8.37. If it put in a limit at 8.45 it would probably get filled pretty quickly since in this bull market the buyers are moving up to meet the sellers book. So it is "losing" the 9c spread for the benefit of making the market look at a casual glance like the sellers are moving down to meet the buyer's book.
Write your own bot to snap those up? Since trading fees are on a percentage basis, it cost almost nothing.
The market will fix this .. spreads narrow and all is right in this world once again.
I thought a bit about doing this... it would take 100 trades to make a BTC (not counting the fees, and if you are lucky the spread will be .10) so not much $ but regardless it would be fun to tweak someone's nose by artificially triggering their bot! It would be interesting to see if it has volume curbs.
BTW the bot has switched sides. It is now pushing the price upwards (it is buying .01 whenever someone sells into an existing bid).
