What are the suggested time periods for the Rate-of-Change?

by Arthur Hill

The default parameter for the Rate-of-Change oscillator is 12-periods, but this can be changed to view rolling performance over a given timeframe. Rate-of-Change measures the percentage change in price over a specified period. A 12-day Rate-of-Change covers about half a month, which is good for short-term traders. 25-day ROC covers just over a month and this is good for swing traders. A 250-day Rate-of-Change covers a year to measure annual changes. This is best suited for long-term investors. There are approximately 250 trading days in a year. Click this image for Read More

This makes it better suited for identifying overbought and Read More

This means prices moved higher after the open. A candlestick has a filled body when the close is below the open, which means prices moved lower after the open. A bearish engulfing pattern consists of two candlesticks. The first Read More

How can I overlay MACD without the histogram?

by Arthur Hill

Indicators can be shown as price overlays by positioning them behind the price. After selecting the indicator in SharpCharts, simply choose “behind price” for the position. Positioning the indicator behind the price makes it easy to see the relation between the indicator and the underlying price. MACD can be positioned behind the price, but the MACD-Histogram can sometimes make the chart look cluttered. Here are the steps to remove the MACD-Histogram and view only MACD with its signal line. First: choose MACD has an indicator. Second: change the number of periods Read More
