why we have 2 colors in darvas boxes? help me to under stand darvas boxes.
A trading strategy that was developed in 1956 by former ballroom dancer Nicolas Darvas. Darvas' trading technique involved buying into stocks that were trading at new 52-week highs with correspondingly high volumes.
A Darvas box is created when the price of a stock rises above the previous 52-week high, but then falls back to a price not far from that high. If the price falls too much, it can be a signal of a false breakout, otherwise the lower price is used as the bottom of the box and the high as the top.
