Example, When i set

Indicator: Simple Moving Average

Hello,

when you place a moving average on a chart for example you can see with an uptrend it raises up under a certain angle. This is the value this indicator “tries” to return. Please keep in mind it is tricky. Angle depends on the zoom of your chart, it is not absolute value only relative. But you can experiment with certain input values and report back your experience with this function

hi,

I want to use EMA slope as regime filter, the MT5 code logic as below, but I create the sqx block code, it seems not work. Cloud you give me some advice?

***********************************************

MT5 CORE CODE:

bool GetEMAAngle_PriceNorm(int shift, int lookback, double &angle)
{
double now, prev;
if(!GetBufferValue(emaHandle, shift, now)) return false;
if(!GetBufferValue(emaHandle, shift + lookback, prev)) return false;
if(prev <= 0.0) return false;

double slope = (now – prev) / (lookback * prev);
angle = MathArctan(slope) * 180.0 *1000 / M_PI;
return true;
}
***********************************************

SQX codeEditor

package SQ.Blocks.Indicators.FilterTrend;

import com.strategyquant.lib.*;

import com.strategyquant.datalib.*;

import SQ.Internal.IndicatorBlock;

import SQ.Blocks.Indicators.MovingAverage.EMA;

@BuildingBlock(

name=”(XXX) EMA_PriceNormAngle”,

display=”EMA_PriceNormAngle(#EMA_Period#,#Lookback#)”,

returnType = ReturnTypes.Number

)

@Help(“EMA price-normalized angle = atan((EMA_now – EMA_prev)/(Lookback * EMA_prev)) in degrees”)

public class FilterTrend extends IndicatorBlock {

// === INPUT PRICE ===

public DataSeries Input; // Close price

public int EMA_Period;

@Parameter(defaultValue=”5″, minValue=1, maxValue=100, step=1)

public int Lookback;

// === OUTPUT ===

@Output

public DataSeries Value;

// === INDICATOR ===

private EMA ema;

@Override

protected void OnInit() throws TradingException {

ema = Indicators.EMA(Input, EMA_Period);

}

@Override

protected void OnBarUpdate() throws TradingException {

if (CurrentBar < EMA_Period + Lookback) {

Value.set(0, 0);

return;

}

double ema_now = ema.Value.get(0);

double ema_prev = ema.Value.get(Lookback);

double angle = 0;

if (ema_prev != 0) {

double slope = (ema_now – ema_prev) / (Lookback * ema_prev);

angle = 1000 * Math.toDegrees(Math.atan(slope));

}

Value.set(0, angle);

}
