I have been following the S&P 500 E-mini for a few months now and I need help developing trading strategies. I have been watching the Youtube videos by SNP500trader and powercharting.com to paper trade support and resistance levels. The trades that I take are not too bad, but days go by where I do not enter trades and miss opportunities. Is there a book or other resource which can provide me with strategies on how to trade CME: ES?
