I found lots of useful advice in CWT podcast #56 with Matt Zimberg (Optimus Futures); specifically, focusing on a select number of indicators for making trading decisions.
Kudos to Aaron for this interview and Chat with Traders, please keep up the great work!
As a result, listed below are ones which I have been successfully using over the past several months:
Volume/Price: Candlestick plot on 60-min and 1-day intervals using the Street Smart charting tool
VWAP: Chart in its own plot within Street Smart, which displays well with the 60-min interval
MACD: Refraining from oscillators to keep things simple, I use just one (MACD) to monitor momentum
