Support and Resistance (Barry) is a VertexFX client side VTL indicator based on the Fractal candles.

A Fractal High candle is a candle whose high has two lower Highs preceding it, and two lower Highs following it. Similarly a Fractal Low candle is a candle whose Low has two higher Lows preceding it, and two higher Lows following it. The Support level is a Fractal Low, whereas a Resistance level is Fractal High. The current Support level remains in place until a new Fractal Low is encountered. Likewise, the current Resistance level remains in place until a new Fractal High is encountered. The Support levels are displayed in BLUE dots, whereas Resistance levels are displayed in RED dots

Juice Levels indicator is a useful VertexFX client side VTL indicator for research and analysis of the trend strength and volatility. It comprises of three components, the Green component which is good strength of the trend. The Red component which is bad (underperforming) trend strength and the Yellow component which is the average trend strength.

Laguerre ROC (Rate Of Change) is a trend based VertexFX client side VTL indicator that has minimal lag.

It should be used in conjunction with other market cycle based indicators to detect the market trends. We first calculate the ROC which is the difference between the current Close and the Close PERIOD bars ago, dividing it by the Close PERIOD bars ago. This value is then smoothed using the GAMMA smoothing constant. Finally, we calculate the up-changes and down changes and the ratio of the cumulative sum of up-changes to down-changes is the Laguerre ROC. It oscillates between 0 and 1. When the value falls towards zero and bottoms out, it implies that the market is preparing for an up move. Likewise, when the value towards one and peaks out, it implies that the market is preparing for a down move.

Kalman Filter indicator is a trend-following VertexFX client side VTL indicator that uses the concept of digital filter based on velocity (speed in price changes), and error correction (eliminating whipsaws and noise).

At first step, we calculate the change in price. This value is smoothed and sharpened with K and SHARPNESS factors. The velocity is calculated based on the threshold and the smoothed values. When the velocity is positive (bullish), the indicator turns BLUE, where as when the velocity is negative, the indicator turns RED.

Fractal AMA (Adaptive Moving Average) is a powerful VertexFX client side trend following VTL indicator that gives excellent entry and exit signals typically on higher (H4 and Daily) time-frames.

There are two components in the indicator – main Fractal AMA indicator (Blue), and the signal indicator which is Red. We calculate the range which is the Highest High minus Lowest Low, over the R_PERIOD, and half of R_PERIOD. Then digital filter is applied to calculate the difference between the logarithms of the ranges for the different periods. Finally it is smoothed using the MULTIPLIER to calculate the main BLUE signal. Likewise, the difference is smoothed using the SIGNAL_MULTIPLIER to derive the signal Red line.

ForexOffTrend indicator is a powerful VertexFX client side VTL indicator for trend following trading systems and markets. It is based on the concept that markets make Higher Highs in up trends and Lower Lows in downtrends.

The indicator uses SSP as the look back period to determine the highest highs and lowest lows. The Highest High and Lowest Low over the specified SSP period are calculated. The indicator is calculated by dividing the difference between the Highest High and Lowest Low by the K_MAX filter threshold.
