Calculating the Moving Average Convergence Divergence (MACD) with JavaScript - DEV Community
December 19, 2022 - Here's an example of how you can implement these formulas to calculate the MACD for a given array of closing prices: function calculateMACD(closingPrices) { const ema12 = calculateEMA(closingPrices, 12); const ema26 = calculateEMA(closingPrices, 26); const macd = ema12 - ema26; return macd; } function calculateEMA(closingPrices, period) { const k = 2 / (period + 1); let ema = closingPrices[0]; for (let i = 1; i < closingPrices.length; i++) { ema = (closingPrices[i] * k) + (ema * (1 - k)); } return ema; } // Example usage const closingPrices = [100, 110, 105, 115, 120, 130, 140, 150, 145, 155]; const macd = calculateMACD(closingPrices); console.log(macd); // Output: -1.33

25 data points is not enough to get a good result. Calculation of an EMA series (MACD is based on multiple sets of EMA series) is recursive. for calculating EMA/MACD, i'd say use at least a year's worth of closing price data.
smoke-screen testing of technical indicator software can be rather arduous since you have to be certain you're using the exact same set of data, ensure you're starting with the same initial priming values, etc., as the reference system/calculation is.
as far as getting the data, yahoo is one option obviously. markit also offers an api that might work which returns historical prices.

MACD histogram is used to differentiate MACD line and signal line. RSI shows how strongly a stock is moving in its current direction. To render a RSI Indicator, use indicator type as Rsi and inject RsiIndicator module using StockChart.Inject(Rsindicator).RSI indicator will be represented by three lines (upperBand, lowerBand, signalLine). The upperBand and lowerBand values are customized by overBought and overSold properties of indicator and the signalLine is calculated by RSI formula.
