The point wasn't that a trade containing that number happened to pop up. It was that the specific number 13076.389 was in the top 50 traded amounts on the exchange.
You'd expect there to be on average the same number of trades for 13076.388 and 13076.390 as there were for 13076.389, but that's not what the numbers show. Unless there is something special about the number 13076.389.
- Declanomous 8y agoFloating point inaccuracy in software someone built to trade?
- lowdest 8y agoWhat I meant was that my code makes hundreds or thousands of trades with the exact same extended decimal number. I'll use that trade size for several days and hundreds of trades per day before I update to another trade size.
- theptip 8y agoAh, got you. That could be it, but then why aren't there artifacts like that in the USD-BTC chart? On that one the prominent trade amounts are 1, 0.1, 0.01, ... as you would expect. Could be that for USD-USDT algorithmic trading is dominant, vs, human trading being dominant in USD-BTC, in which case arbitrary amounts like 1, 0.1,.. would be less common for the USDT case. I'm not sure how to assess this though.
- lowdest 8y agoThat's basically my guess. Since volume is comparatively low on Kraken USD-USDT, an algorithmic trader with a large bankroll clearly stands out. It might be one of the parties with a financial interest in maintaining the USD parity, or it could just be someone placing bets that the parity will continue.
