Anyone else have GDAX limit orders cancelled recently?
Over the last year, I've made a decent number of GDAX USD/LTC limit orders set to good-till-cancelled, time-in-force at various levels below market price. Recently, I logged in and found all of my orders on the books disappeared and the USD amount returned to my USD wallet. I have not personally cancelled any of these so I can only gather that:
1. GDAX/Coinbase has cancelled and returned these.
2. Some technical glitch that caused this.
Since orders are Price-Time priority, this negates my original opportunity/cost decision and I'm not happy about this.
Any advice on how I might deal with this? Have the rules changed?
