I found out the hard way in order to trade any crypto and/or currency pairs, you MUST be "on call" 24 hours a day!  What I mean by that is the following:  You MUST set alarms for whatever crypto or currency pairs you trade.  Your alarms will be set for points NEAR entry or NEAR exit.  Your alarm can sound at anytime, even while sleeping.  When sleeping is the worst    but I deal with it.

Features I like on BitFinex are the ability to make the following orders:  Limit order, Market order, Stop order, Trailing Stop order and Fill or Kill order.  This takes alarms out to a certain extent but I still like to create alarms as a precaution.  I also like the ability to "HIDE" your order so it does not appear on the order book for all to see and make decisions that could affect your position since you have "exposed" your position.  Especially, if your position is a large order.

I've also found tradingview.com to be a valuable tool when making decisions for trades.  There is a wealth of information on tradingview.com.  I love the chat box to talk to serious traders about trading.  You can "follow" traders with high ratings from other members, look at their charts they publish for all to see with ideas explaining their position on the charts, etc...  If you choose to sign up at tradingview.com, my username is ProwdClown.
