Build a line of defense for micro-quantitative trading, and use multi-dimensional indicator resonance and asset low correlation to hedge and smooth drawdowns! This article provides in-depth science on the long- and short-term switching strategy between the 20/60/200-day moving average and static support and resistance in Contracts for Difference (CFD) trading, and dissects the resonance model of MACD momentum changes and RSI overbought and oversold entry signal resonance models. Comprehensively explore the slippage risks during data windows such as non-agriculture and interest rate decisions, and detail how to use cross-market allocation and zero-threshold simulation to hone the iron law of survival.
