🆓 Smoothed Chande Trend Score w/ Signal Line by Cryptorhythms

👀Did not see this one in the public library yet, so here you go! I added an ema signal line that you can configure the length on. Also dressed it up a little with OB/OS zones and some purdy colors.

Here are long + short charts:

Description written by Chande...

As you may have noticed, a number of rather complicated indicators are available to measure trend strength. None of these indicators, unfortunately, is perfect. You could use J. Welles Wilder's average directional index (ADX) as an indicator of trend strength, or perhaps the r² value from linear regression analysis. Or you could even use the vertical horizontal filter (VHF) to help determine whether the market is trending.

Each of these indicators requires the user to determine how many days' data should be used in the calculations. As you vary the indicator length or number of days used in the calculation, however, the result of the calculation changes also. Thus, there is no unambiguous answer. If the market were about to enter or leave a trading range, you could get a different indication of trend strength every day — a frustrating set of circumstances.


RATING THE TREND

Here is my way of rating a trend, a method I call trendscore.

Add up the score for 10 comparisons; the score varies from + 10 to -10. If today's close is greater than all the previous closes, then the trend's score is +10; if today's close is less than all the previous closes, the score is -10. You can smooth the data by adding fewer than 10 days or more than 10 days. A positive score shows an upward trend bias. Similarly, a negative score shows a downward bias. A shorter time of comparison may be too volatile, producing frequent trend change signals, while a longer comparison time is slow to respond. During long trends, the trendscore remains at the outer limits, +10 or -10, for the duration of the trend. In sideways markets, the score doesn't remain at +10 or -10 for long, oscillating between these limits.

How to Use this Indicator

You could trade the trendscore many ways. You could use the zero crossing as an early signal. You would then buy when the trendscore becomes positive and sell when it becomes negative. Or you could wait one to three days after the trendscore reaches +10 or -10 before buying (+ 10) or selling (-10) . Or you could combine the trendscore with a moving average, trading an upward or downward cross over.

Another variation would be to go long after the trendscore crosses from -10 to above +5 and go short after the trendscore falls from +10 to below 5. The approach you choose depends on your trading style. You could also smooth the trendscore with more or fewer days than I used in my calculations. You could, for example, use fewer than 10 days for short-term and 20 to 30 days for intermediate-term trading. You could also combine trendscore with other indicators of trend strength. For example, if you combined it with the VHF indicator, trendscore would provide an indication of direction, while the VHF could provide additional information about the trend's strength. You could also substitute intraday data in the trendscore method for short-term trading, using hourly data to calculate a trend's score instead of daily data. Trendscore is a simple way to rate trend strength. It indicates both the direction and strength of the trend and can be easily combined with various trend-following strategies.
