Zweig Market Breadth Thrust Indicator [LazyBear]

The Breadth Thrust ( BT ) indicator is a market momentum indicator developed by Dr . Martin Zweig. According to Dr . Zweig a Breadth Thrust occurs when, during a 10-day period, the Breadth Thrust indicator rises from below 40 percent to above 61.5 percent.

A "Thrust" indicates that the stock market has rapidly changed from an oversold condition to one of strength, but has not yet become overbought. This is very rare and has happened only a few times. Dr . Zweig also points out that most bull markets begin with a Breadth Thrust.

All parameters are configurable. You can draw BT for NYSE, NASDAQ, AMEX or based on combined data (i.e., AMEX+NYSE+NASD). There is also a "CUSTOM" mode supported, so you can enter your own ADV /DEC symbols.
