הרעיון במילים פשוטות

If a little volume moves the price a lot, the market is "easy" to move in that direction. Comparing this efficiency with volume reveals four situations: a strong move (green), a fading move, a fake move and a pause before a breakout ("squat").

איך זה מחושב

Candle range divided by volume. Colour: green if both rose, brown if both fell, blue if the index rose but volume fell, pink if the index fell but volume rose.

BW MFI = (high − low) ÷ volume
Green: MFI ↑ volume ↑   Brown (fade): MFI ↓ volume ↓
Blue (fake): MFI ↑ volume ↓   Pink (squat): MFI ↓ volume ↑

איך משתמשים בזה

  • Green bars: join the move.
  • Pink (squat) bars: a battle before a breakout; watch which way it breaks.
  • Brown bars: interest is fading; the move may end soon.

הסקת מסקנות

  • Most useful at the edges of ranges and after strong moves.

דוגמה

Near a resistance level the BW MFI prints a pink bar: heavy activity but little movement. The next candle breaks the level with a green bar.

ממה להיזהר

  • On currencies, metals and CFDs there is no central exchange volume. The chart uses "tick volume", the number of price changes in each candle, which follows real activity closely but is not the number of contracts traded.
