NTR Reverse is VertexFX client side VTL Expert Adviser. NTR Reverse EA is based on trading range breakout strategy. The breakout range is calculated as the trading range of the most recent bars, determined by the parameter “per”. Default value for trading range is 3 bars. The EA avoids choppy breakouts by applying a ATR or fixed pips based filter to the breakout level. When the high of the trading range is broken upward, a buy position is opened. When the low of the trading range is broken, a sell position is opened.

Parabolic SAR Colored With Alert is a Client Side VTL Alert. It is an improvement over the standard parabolic stop and reverse indicator.

RFTL (Reference Fast Trend Line) is a powerful trend-following VertexFX indicator which responds quickly to price fluctuations.

It is a digital filter based indicator, designed from FLF-1 and FLF-2 digital filters from discrete input sequence. In Digital Signal Processing theory, prices are considered to be based of two components – the signal component – which is the main trend, and the noise component – which is the whipsaws and sideways movements.

T3 RSI is a VertexFX client side VTL indicator based on RSI indicator, and is calculated using the T3 smoothing methodology.

The smoothing attempts to reduce the lag and provide the trading trigger. T3 RSI indicator is made from two components; the RSI (white) which is the standard RSI calculated using the RSI_PERIOD, the second component is the T3 RSI (red), which is calculated by smoothing the RSI using the T3 smoothing method using the T3_PERIOD and T3_CURVATURE as the smoothing constant. Both of these indicators are plotted together, and the T3 RSI (red) provides as the signal trigger to the standard RSI.

Least Square MA is a moving average based VertexFX client side VTL indicator that employs least-square’s, best-fit model. In the least squares best-fit methodology, given a number of points, we find an ideal line which is close to all points.

LWMA Crossover Signal indicator is a VertexFX client side VTL indicator based on a fast moving and slow moving Linear Weighted Moving Average indicator (LWMA).

Schaff Trend Cycle is a VertexFX client side VTL indicator used to determine the two important characteristics of a trend – mainly its strength, and its cycle.

Zero Lag MACD indicator is a VertexFX client side VTL indicator based upon the MACD. It attempts to eliminate the lag that is inherent in MACD indicator by using two levels of filtering. It comprises of two components, the MACD component (MAGENTA histogram), and the Signal component (ORANGE line).

To calculate the MACD component, we first calculate the fast and slow EMA based on FAST_EMA and SLOW_EMA periods. We once again calculate the fast EMA of the calculated fast EMA using the FAST_EMA period, and the slow EMA of the calculated slow EMA using the SLOW_EMA period. The fast EMA lag is calculated as,

RAVI is a simple VertexFX client side VTL indicator but innovative one based on Simple Moving Averages. The idea behind RAVI is that faster SMA responds quicker to market changes compared to slower SMA.

It is calculated by dividing the difference between the faster SMA and the slower SMA by the longer SMA. When markets are rising, the difference between faster and slower SMA increases quickly and hence RAVI rises. When the market reaches saturation top, this difference starts reducing and the RAVI peaks out – signaling a market top.

Kaufman indicator is a VertexFX client side VTL indicator which employs a variation of the Adaptive Moving Average (AMA), to generate precise trade signals. It also uses concepts of digital filters and signal-to-noise (SNR).

The first step, is to calculate the absolute difference between the current price and the price KAUFMAN_PERIOD bars ago.
