[blackcat] L1 Richard Poster Trend PersistenceLevel 1
Background
In Traders’ Tips of February 2021, the focus is Richard Poster’s article in the February 2021 issue, “Trend Strength: Measuring The Duration Of A Trend”.
Function
In his article in this issue, Richard Poster outlines several common ways to evaluate the strength and duration of trends. Then he evaluates their sensitivity to volatility. Next, he steps up our game a bit by proposing an indicator that seeks to measure a trend’s persistence rate, or TPR for short. TPR turns out to be relatively insensitive to the influence of volatility.
Financial markets are not stationary; price curves can swing all the time between trending, mean-reverting, or entire randomness. Without a filter for detecting trend regime, any trend-following strategy will bite the dust sooner or later. In his article in this issue, Richard Poster offers a trend persistence indicator (TPR) for helping to avoid unprofitable market periods.The TPR indicator measures the steepness of a SMA (simple moving average) slope and counts the bars where the slope exceeds a threshold. The more steep bars, the more trending the market. Threshold, TPR period, and SMA period are the parameters of the TPR indicator.
Remarks
This is a Level 1 free and open source indicator.

TPR
Trend Pullback Reversal TPRThe TPR(Trend Pullback Reversal) indicator forms a possible price trend with support and resistance lines. It also comes with a unqiue band and center line as additional features.
TPR works on all timeframes and all symbols and all type of bar chart.
TPR never repaints.
There are 4 Parameters:
Period: umber of bars used for calculations
Factor: Multiplier factor, small number for short trend, large number for long trend
Source: the input series, default is Close
ShowBand: enable to show band and center line
Most trend indicators have similar plot, the difference is where and when they change the direction. Unlike other trend indicators, TPR will focus on main trend and filter out most minor price movements. The green cross-line represents an uptrend, the red cross-line represents a downtrend.
The additional band and center line may look like bollinger band, but the TPR band algorithm is completely different from bollingerband. There is no standard deviation in TPR band calculation.
