Gold Oscillator using SPX & DXY to measure the moving average cross of the 3.
Gold in Orange
DXY in Green
SPX in Blue
To use this indicator, you need to see the strength (Orange above the 50%) line, use your own configurations and settings for the two MA's as a cross.
The idea is not to enter trades but to know when either SPX or/and DXY is getting stronger or weaker to help with profit-taking of gold positions.
As per any Oscillator - look for patterns, cross-overs and momentum shifts. (Treat like a MACD, RSI or Stochastic).
