Market Maker or some exchange we don't know of yet that is playing margin on Stamp (like coinarch on Finex).
Stamp does not offer margin as far as I know. Also, it seems to be giving away money with every trade. Odd behaviour for a market maker ...
Can you say more about coinarch on Finex? I don't know anything about that
This is getting OT, but could it be Stamp doing fee-less arb with other exchanges or allowing certain market makers to arb without fees?
Yeh, sorry for the e OT, but i think its important here as Masterluc has highlighted it himself as 'Unusual volume activity near weekly 200 sma'. If there was arb, the other side would show up as increased volume on another exchange
FWIW, here are the last 6 trades from that bot, (from Bitcoinwisdom)
15:50:41 239 49.99 buy
15:53:13 238.14 49.99 sell
15:58:01 239.13 49.99 buy
16:02:04 237.65 49.99 sell
16:10:16 238.98 49.99 buy
16:11:49 237.72 49.99 sell
Can't see how this could be arb - no other market is even moving and this bot is creating the relative 'volatility' on Stamp, lifting offers and hitting bids and giving away money ... (*IF* it is the same entity every time)
