1)OHLC(Open low high close) Chart:
Open-high-low-close Charts (or OHLC Charts) are used as a trading tool to
visualise and analyse the price changes over time for stocks, commodities, etc. OHLC
Charts are useful for interpreting the day-to-day sentiment of the market and forecasting any
future price changes through the patterns produced.
The y-axis on a OHLC Chart is used for the price scale, while the x-axis is for a time
scale. On each single time period, a OHLC Charts plots a symbol that represents two ranges:
the highest and lowest prices traded, and also the opening and closing price on that single time
period (for example in a day).
On the range symbol, the high and low price ranges are represented by the length
of the main vertical line. The open and close prices are represented by the vertical
positioning of tick-marks that appear on the left (representing the open price) and on
right (representing the close price) sides of the high-low vertical line.
Colour can be assigned to each OHLC Chart symbol, to distinguish whether the
market is "bullish" (the closing price is higher then it opened) or "bearish" (the closing
price is lower then it opened).
