The Market Facilitation Index technical indicator (BW MFI) shows a price change on one tick. The absolute indicator values themselves mean nothing, only the indicator changes make sense. Bill Williams attaches great importance to changes in the indicator and volume:

  • The Market Facilitation Index indicatorrose and the volume rose too, this means that:
    a) more and more players are entering the market (the volume is growing)
    b) newly arriving players are opening positions in the direction of thebar’s development, i.e. the movement has begun and is gaining speed.
  • The Market Facilitation Index indicatorfell and the volume fell too. This means that the market participants lostinterest.
  • The Market Facilitation Index indicatorrose, but the volume fell. The market is not supported by the volume fromtraders, and the price changes thanks to speculations offloor traders (intermediaries: brokers and dealers).
  • The Market Facilitation Index indicatorfell, but the volume rose. A battle between bulls and bears takes place,with a large volume of buys and sells, but with a slight movement of theprice itself due to approximately equal forces. One of two opposing sides(buyers vs sellers) will win. Usually a breakout of such a bar indicateswhether this bar determines the trend continuation or the trend iscanceled. Bill Williams call such a bar “crouching”.
