Heiken_Ashi_V
Download script
This tool is designed to transform the standard price charts used in trading into Heiken Ashi candles. Unlike traditional Japanese candlesticks, which display raw price data, Heiken Ashi candles use a smoothed average of price action to provide a clearer visual representation of market trends and momentum.
How the Logic Works
The script processes historical market data to calculate four distinct values for every candle: the Open, High, Low, and Close prices. However, instead of using the raw numbers provided by the exchange, it applies specific mathematical formulas:
- Opening Price Calculation: The tool calculates the opening price by taking an average of the previous candles' highs and lows. By looking back over a customizable number of bars (defined by the user), the script "smooths out" sudden price spikes, making it easier to identify the underlying direction of the market.
- Closing Price Calculation: The script offers two different methods for determining the closing price. It can calculate this based on a simple average of the current candle's high, low, and closing prices, or it can include the opening price in that average as well. This allows users to choose how much "weight" the current period's volatility should have on the final visual output.
- High and Low Extremes: To ensure the candles accurately represent the full range of price movement, the script compares the calculated "Heiken Ashi" open and close prices against the actual highest and lowest prices reached during that time frame. It then selects whichever values are the true extremes to form the boundaries of the candle.
Visual Representation
The logic concludes by assigning these calculated values to four different visual buffers:
- Body Boundaries: It determines the upper and lower bounds of the candle body based on whether the price moved up (Close is higher than Open) or down (Open is higher than Close).
- Reference Points: It stores the smoothed Open and Close values used for the calculations.
By using these averages rather than raw data, the resulting chart helps filter out "market noise," making it easier for a trader to see whether the trend is currently bullish, bearish, or moving sideways.
