Momentum (SDK Trading)

Momentum and rate of change are simple technical analysis indicators showing the difference between a day(or a certain time period)'s closing price and the close N days(or some specific time periods) ago. It measures the latest closing bar to a previous closing bar N periods ago. By analyzing the rate of change, we can gauge the strength or so-called “Momentum” in a financial instrument or Forex currency pair.
