Momentum Acceleration by DGTItalian physicist Galileo Galilei is usually credited with being the first to measure speed by considering the distance covered and the time it takes. Galileo defined speed as the distance covered during a period of time. In equation form, that is v = Δd / Δt where v is speed, Δd is change in distance, and Δt is change in time. The Greek symbol for delta, a triangle (Δ), means change. Is the speed getting faster or slower? Acceleration will be the answer, acceleration is defined as the rate of change of speed over a set period of time, meaning something is getting faster or slower. Mathematically expressed, acceleration denoted as a is a = Δv / Δt , where Δv is the change in speed and Δt is the change in time. How to apply in trading Lets think about Momentum, Rate of Return, Rate of Change all are calculated in almost same approach with Speed Momentum measures change in price over a specified time period, Rate of Change measures percent change in price over a specified time period, Rate of Return measures the net gain or loss over a specified time period, And Speed measures change in distance over a specified time period So we may state that measuring the change in distance is also measuring the change in price over a specified time period which is length, hence speed can be calculated as (source – source )/length and acceleration becomes (speed – speed )/length In this study acceleration is used as signal line and result plotted as arrows demonstrating bull or bear direction where direction changes can be considered as trading setups Just a little fun, since we deal with speed the short name of the study is named after famous cartoon character Speedy Gonzales Trading success is all about following your trading strategy and the indicators should fit within your trading strategy, and not to be traded upon solely Disclaimer: The script is for informational and educational purposes only.

Percentage Of Rising MA'sReturn the percentage of rising moving averages with periods in a custom range from min to max , with the possibility of using different types of moving averages. Settings Minimum MA Length Value : minimum period of the moving average. Maximum MA Length Value : maximum period of the moving average. Smooth : determine the period of an EMA using the indicator as input, 1 (no smoothing) by default. Src : source input for the moving averages. Type : type of the moving averages to be analyzed, available options are "SMA", "WMA" and "TMA", by default "SMA". Usages The indicator can return information about the main direction of a trend as well as its overall strength. A value of the indicator above 50 implies that more than 50% of the moving averages from period min to max are rising, this would suggest an uptrend, while a value inferior to 50 would suggest a down-trend. On the chart, a ribbon consisting of simple moving averages from period 14 to 19, with a color indicating their direction, below the indicator with min = 14 and max = 19 The strength of a trend can be determined by how close the indicator is to 0 or 100, a value of 100 would imply that 100% percent of the moving averages are rising, this indicates a strong up-trend, while a value of 0 would suggest a strong down-trend. Using different types of moving averages can allow to have more reactive or on the contrary, less noisy results. Here the type of moving average used by both the ribbon and the indicator is the WMA, the WMA is more reactive than the SMA at the cost of providing less amount of filtering. On the other hand, using a triangular moving average (TMA) provide more filtering at the cost of being less reactive. Finally, irregularities in the indicator output can be removed by using the smooth setting. Above smooth = 50. Details The indicator is based upon a for loop, this implies that both the sma, wma or change functions are not directly usable, fortunately for us, it is possible to get the first difference of both the SMA, WMA and TMA without relying on a loop by using simple calculations. The first difference of an SMA of period p is simply a momentum oscillator of period p divided by p , there are two ways to explain why this is the case, first, simple math can prove this, the first difference of an SMA is given by: (x + x + ... + x )/p - (x + x + ... + x )/p The repeating terms cancel each other out, as such, we end up with (x - x )/p which is simply a momentum oscillator divided by p , since this division doesn't change the sign of the output we can leave it out. We can also use impulses responses to prove this, the impulse response of a simple moving average is rectangular, taking the first difference of this impulse response will give the impulse response of a momentum oscillator, with the only difference being that the non-zero values of the result will be equal to 1/p instead of 1. The same thing applies to the WMA above the impulse response of the first difference of a WMA, we can see it is extremely similar to the one of a high pass SMA, only 1 bar longer, as such we can have the first difference of a WMA quite easily. The TMA is simply a 2 pass SMA (the SMA of an SMA), as such the solution is also simple.

Attributable VolumeA volume indicator which calculates "Attributable Volume”, the portion of volume which contributed to the direction in which the candle moved. Attributable Volume is calculated as: Total volume excluding the "counter wick" volume. Where for a green (up) candle, the "counter wick" volume is the top wick volume. In theory, Attributable Volume should better represent the effort of directional thrust of each candle. By default, this indicator displays “Attributable RVOL”, but can be set to: Attributable RVOL RVOL Attributable Volume Volume Note: RVOL = Relative Volume, the current volume divided by the Volume moving average. RVOL can be used to identify major moves, and potential starts/ends to trends.

Direction&Strength Indicator This simple Indicator shows: (1) The D irection of a trend (2) The S trength of a trend hence the name "Direction & Strength Indicator. How to read this Indicator: Indicator above "resistance area" => strong UP trend Indicator above 0 .................. => weak UP trend Indicator below 0 .................. => weak DOWN trend Indicator below "resistance area" => strong DOWN trend Notice that this is a time-lagging indicator. Severity of timelag depends on set period of the indicator! You can also identify overbought and oversold areas. (Tip: Compare to RSI.)

B3 Directional Trend IndexB3 Directional Trend Index ~ All about the trend! William Blau is the designer of this gem, and IMHO it is the best trend finder of all the lagging indicators out there I have tested. It is important to pay attention to the slope and thickness of the line, and its relationship to zero. A reversion to the zero may look momentous, but in fact it could reverse when it reaches mean, only to turn back around. You can see this in March and April of this silver futures daily chart. Makes for a great instrument on anything you consider trendy, like crude oil for example. The default user inputs are set to my liking, as I find them to be great on all charts and resolutions. You may read around to find more about this on the internet, or its mentioned in Krausz's work. Also, imprtant to remember when no trend, trend finders like this sufffer, so be wise as to what market condition you are in. Rangy and within Range = no, On the Move = yes.
