On Balance Volume adds volume on up days and subtracts it on down days. When OBV breaks out to a new 63-day high while the price is still at least 3% below its own 63-day high, volume is leading price: buyers are absorbing supply before the breakout shows on the chart. This screen lists stocks on the London Stock Exchange with that bullish volume lead. Many traders watch these names for a price breakout to confirm. LSE prices are quoted in pence, and the list skips thinly traded shares.
