The futures trading system is similar to the ones that trades equities. We look for exhaustion ( oversold/overbought) levels against key support and resistance levels and then looking for signs of buyers/seller stepping in. This process is about 90% automated because the system spits out the Buy or Sell signal and then the actual trade is placed manually after we do a quick check of the context.
