Web Trader MT5
A market rally may look impressive even when only a few large stocks are rising. The Zweig Breadth Thrust checks whether the strength is spreading across a much wider part of the market.
The indicator compares the number of advancing shares with the total number of advancing and declining shares, then smooths the result over ten days. A signal appears when the reading rises from below 40% to above 61.5% within ten trading days.
A move from 36% to 63%, for instance, shows a rapid shift from weak participation to broad buying across many stocks. The signal was developed by Martin Zweig and appears rarely, which is one reason technical analysts pay attention when it occurs.
