As per this survey:
These are three I am going to initially focus on:
ARIMA-currently being worked on but still heavily until quant analysis through time series
Moving Average-pretty popular technical strategy that people get, looks easy to implement
Pairs Trading-same reasons as moving average
The other strategies listed are pretty advanced which are heavy math based and really use for quant analytics. This could take months to get to this point.

NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
