That's what really screwed me. I had a few limit buys, but was relying on notifications for deep dives and got royally screwed on a couple trades. Doubled up transactions because of erroneous failed orders, completely missed pulling some profit on the first rebound, and by the time the market bottomed out below 300 I was so frustrated I had already walked away. That was all through their website! I gave up on trying to go through Coinigy and the API early on.
Luckily I've got some more money that just made it into the exchange or I'd be stuck hodling till the market recovers
