Triple Coppock CurveThe Coppock Curve is a zero-centered momentum oscillator that relies primarily on rate of change calculations. The Coppock Curve in its most basic form is already a great indicator, especially for spotting shifts in momentum. But, we wanted to see how we could modify it to get some better performance out of it.
As the ‘cop’ function demonstrates, the Coppock Curve has a pretty simple calculation. The first step is to calculate the rate of change at a longer and shorter window length. Next, the sum of the two rate of change values is calculated and finally a weighted moving average of a user defined length is calculated(this is the Coppock Curve).
The ‘cop()’ function set the foundation to allow us to implement our modifications. As you can see in the graph, there are 3 different lines (2 histogram and 1 normal line) comprising the Coppock values based on the rate of change of high, low, and closing prices. We liked this layout because it allows traders to easily identify the curve’s pivots and the balance of negative vs. positive momentum.
The Coppock Curve based on high prices is plotted as the teal histogram, wile the pink histogram represents the Coppock Curve of low prices. The curve based on closing prices is the red and green alternating line plotted on top of the two histograms.
We included some notes on the chart to help with interpreting the three curves.
There are two common approaches traders can take when trading with the indicator:
1. Trade based on closing price curve: Go long when line changes from bearish(red) to bullish(green). Then, go short when same line changes from bullish to bearish.
2. Trade based on crossings of the zero-line. This could be based on the high, low, or closing price curves, but closing price is the safest bet. So, go long when it crosses from negative into positive territory and short when it crosses under the zero line from positive into negative territory.

Vortex Trend TrackerThough it may sound complex, the Vortex Indicator is essentially an uptrend line and a downtrend line. The vortex indicator can be used for a variety of purposes, including tracking the strength of trends, identifying/anticipating reversals, and generating entry/exit signals. It’s calculation is shown in the open-source code below.
To reduce the number of whipsaws produced by the indicator, we used an Exponential Moving Average of vmPlus and vmNegative values with a default length of 10. Decreasing this length will result in a more responsive vortex at the cost of more whipsaws and false signals.
The chart shows the absolute value of the difference between the uptrend and downtrend line displayed as the main histogram.
If the uptrend line is greater than the downtrend (thus indicating positive movement), then the histogram bars will be either light green or dark green. If the uptrend line has just now crossed the downtrend line, then the bar will be dark green. Bars will also be dark green when the uptrend line is greater than the downtrend line and the uptrend line is increasing. This means the trend is increasing in strength still. If the uptrend line is greater than the downtrend line, but is decreasing, then the bars will be light green. This means that the upwards trend is losing strength.
If the downtrend line is greater than the uptrend line, then there is a negative trend occurring and the bars will be either red or light red. If the downtrend line has just crossed over the uptrend line or is increasing in value, then the bar will be red. If the downtrend line is greater than the uptrend line, but is decreasing in value, then the bars will be light red (meaning the downtrend is weakening).
One way to trade using this vortex is to enter a long position when the bar color changes from red to light red. This would mean that the downtrend is decreasing in strength and an upwards reversal is likely to occur soon. Then, traders can exit their long position when the bars change from dark green to light green. When that color change occurs it means that the uptrend is running out of steam and price is unlikely to continue its upwards climb.
Traders can also choose to have the uptrend and downtrend lines plotted as well in the input menu. This may make it easier to visualize the Vortex and its usefulness in identifying reversals.

VWMA/SMA Breakout and Divergence DetectorThis indicator compares four different values :
-Fast Simple Moving Average(SMA)
-Fast Volume Weighted Moving Average(VWMA)
-Slow SMA
-Slow VWMA
Comparing SMA's and VWMA's of the same length is a common trading tactic. Since volume is not taken into consideration when calculating Simple Moving Averages, we can gain valuable insights from the difference between the two lines.
Since volume should be increasing along with an upwards price movement, the VWMA should be greater than the SMA during a volume-supported uptrend. Thus, we can confirm an uptrend if the VWMA remains greater than the SMA. If the VWMA falls under the SMA in the midst of an upwards price movement, however, that indicates bearish divergence. The opposite is true for downtrends. If price is decreasing and volume is decreasing at the same time (as it should), then we can confirm the downtrend.
Interpreting the Graph:
If the slow SMA is greater than the slow VWMA, then the area representing the difference between the two lines is filled in red. If the slow VWMA is greater than the slow SMA, however, the area between the two is filled green.
If the fast SMA is greater than the fast VWMA, then the area between the two dotted lines is filled in red. On the other hand, the area will be filled green if the fast VWMA is greater than the slow SMA.
In addition to spotting divergences and confirming trends, the four lines can be used to spot breakouts. Typically, a VWMA crossover will precede the SMA crossover. When the fast VWMA crosses over the slow VWMA and then a SMA crossover follows shortly after, then it is a hint that a bullish trend is beginning to form.
