Martin Pring on price patterns
I also recommend james16 chart thread from forex factory if you want to really be good at price action trading.
Don't pay for anything with the exception of books. You can find all informations for free. You don't even need Martin Pring on price patterns to be honest if you read the james16 chart thread.
From babypips school you should read especially these 2 articles:
School of Pipsology Support and Resistance Levels
School of Pipsology Important Chart Patterns
From indicators I only use 150 and 365 EMA (they can sometimes act as support/resistance) and MACD (for divergence). But they are not very important, you can trade price action without indicators without problems.
