RE: bullish signal - MACD10 Jun 2020 21:19
Check out the Charts function and the technical indicators.
From WIKI: MACD, short for moving average convergence/divergence, is a trading indicator used in technical analysis of stock prices, created by Gerald Appel in the late 1970s. It is designed to reveal changes in the strength, direction, momentum, and duration of a trend in a stock's price.
Basically, on IMB today two lines crossed that indicate there's more probability that the SP moves northwards. It's not set in stone it's all about probability and it's one indicators technical traders keep an eye to.
