aahh. predictions   bound to make a fool out of all of us.  SMSCs befor and after candlesticks suggest you did the right thing.  A too rapid rise nearly always means a rapid retrace as the herd (that was you today or part thereof) was bound to take some short term profits.

by predictions is that there is corporate action at play here and the future BFS and financing will decide the longer term trend pending pog holding up preferably above $US1300. The daily chart was showing overbought and hence a short term sell.  The weekly though is strong and looks to consolidate or move a little higher in the medium term.  A retrace though to low 20c may well be on the cards.

If, like a sydney realestae auction in 2016, there is multiple corporates interested the NST will protect their investment and anything could happen.

Also everything depends on what your investment plan is . Day trading is not my go as I don't have the software or interest or time to be sitting on the screen all the time the market is open.  Hence medium term trend analysis with stop losses is a good strategy imo.  Too many hate the small losses which lead to bigger losses so a simple 10% or a TA on support levels will be a good thing to automate into your platform.  Tailing stop losses are also good however they can sought out by instos and sophisticated traders to cause a catalyst for stock drops with view to preying on retail punters.  It also depends on position size and how nimble you want to be.

Anyway getting back to predictions, my view is to simply do what you did today and take the profit when the stock rises too quickly and possibly buy back in when you feel the market tells you it is time.  ie over sold. etc
