Black crosses mark the 'golden crosses' as well as the 'death crosses'. These black crosses appear when the 30 crosses the 100 & when the 100 crosses the 200. These black crosses don't tell you when to buy/sell, but simply indicate interest in the market.
This code is open-source so feel free to add this indicator to your chart and play around with the different moving average timeframes & color schemes.
Golden Cross The golden cross occurs when a short-term moving average crosses over a major long-term moving average to the upside and is interpreted by analysts and traders as signaling a definitive upward turn in a market. Basically, the short-term average trends up faster than the long-term average, until they cross.
There are three stages to a golden cross:
A downtrend that eventually ends as selling is depleted
A second stage where the shorter moving average crosses up through the longer moving average
Finally, the continuing uptrend, hopefully leading to higher prices
Death Cross Conversely, a similar downside moving average crossover constitutes the death cross and is understood to signal a decisive downturn in a market. The death cross occurs when the short term average trends down and crosses the long-term average, basically going in the opposite direction of the golden cross.
The death cross preceded the economic downturns in 1929, 1938, 1974, and 2008.
