I used to trade on Bitfinex and recently switched to Prime XBT which also has OCO orders. Bitfinex gave me a taste for small scale leverage trading and shorting - but with the recent state of the sideways market, I've upped my game with higher leverage (Prime XBT offers up to 100x) to amplify small price actions without putting all my capital on the line.  This allows me to hedge my portfolio with diversification to reduce risk.  Other orders include stop-loss, protection, market, limit, and OCO as mentioned.
