GetMA

Calculates Moving Average value for the current symbol and timeframe.

Syntax

GetMA(
    index: number,
    ma_shift: number,
    period: number,
    maMethod: E_MAType,
    appliedPrice: TPriceType,
    prev?: number
): number

Parameters

Parameter	Type	Description
index	number	Index of the bar to calculate MA for
ma_shift	number	MA shift in bars
period	number	MA period
maMethod	E_MAType	Moving average method (SMA, EMA, SMMA, LWMA)
appliedPrice	TPriceType	Type of price to use (Open, High, Low, Close, etc.)
prev	number	Optional. Previous MA value for optimization

Return Value

Returns a number representing the calculated moving average value.

Description

The GetMA method calculates the Moving Average value for the current symbol and timeframe. It supports different MA types and can be optimized by providing the previous MA value.

Available MA Methods (E_MAType):

• Simple Moving Average (SMA)

• Exponential Moving Average (EMA)

• Smoothed Moving Average (SMMA)

• Linear Weighted Moving Average (LWMA)

Available Price Types can be found in the TPriceType section.

Example

// Calculate Simple Moving Average
const sma = this.api.GetMA(0, 0, 20, E_MAType.MODE_SMA, TPriceType.PRICE_CLOSE);
console.log(`20-period SMA: ${sma}`);

// Calculate Exponential Moving Average
const ema = this.api.GetMA(0, 0, 14, E_MAType.MODE_EMA, TPriceType.PRICE_CLOSE);
console.log(`14-period EMA: ${ema}`);

// Calculate MA with shift
const shiftedMA = this.api.GetMA(
  0,
  5,
  10,
  E_MAType.MODE_SMA,
  TPriceType.PRICE_CLOSE
);
console.log(`10-period SMA shifted 5 bars: ${shiftedMA}`);

// Calculate multiple MAs for trend analysis
const fastMA = this.api.GetMA(
  0,
  0,
  10,
  E_MAType.MODE_EMA,
  TPriceType.PRICE_CLOSE
);
const slowMA = this.api.GetMA(
  0,
  0,
  20,
  E_MAType.MODE_EMA,
  TPriceType.PRICE_CLOSE
);

if (fastMA > slowMA) {
  console.log("Upward trend detected");
} else if (fastMA < slowMA) {
  console.log("Downward trend detected");
}

// Optimize calculations using previous value
let prevMA = this.api.GetMA(
  1,
  0,
  20,
  E_MAType.MODE_EMA,
  TPriceType.PRICE_CLOSE
);
for (let i = 0; i < 10; i++) {
  prevMA = this.api.GetMA(
    i,
    0,
    20,
    E_MAType.MODE_EMA,
    TPriceType.PRICE_CLOSE,
    prevMA
  );
  console.log(`EMA at bar ${i}: ${prevMA}`);
