FTLM-STLM_v3

This technical indicator is designed to analyze price action by calculating two distinct types of signals based on historical closing prices. It visualizes these results in a separate window on your trading chart, using a combination of a histogram and a line graph to help identify market trends and momentum.

Core Logic and Methodology

The script operates by examining a specific window of recent price history (up to 90 previous bars). Instead of looking at the current price in isolation, it applies complex mathematical weighting to these historical data points to derive two different "values":

1. The Primary Trend Analysis (Histogram) The indicator calculates a first value by assigning specific positive and negative weights to various price points in the past. This creates a "smoothed" representation of market movement. By subtracting a second, more volatile weighted calculation from this first one, the script generates a histogram.

  • Visual Goal: The histogram typically helps traders see the "strength" or "velocity" of a move. When it pushes significantly in one direction, it suggests that the current trend has underlying momentum.

2. The Secondary Trend Analysis (Line) Simultaneously, the script performs a much broader calculation involving even more historical data points (reaching back further than the first calculation). It combines two large sets of weighted averages to produce a single output line.

  • Visual Goal: This line acts as a secondary filter or "anchor." Because it uses a wider range of data, it is less reactive to sudden, "noisy" price spikes and focuses more on the broader directional flow of the market.

How It Works Together

The logic follows a "Difference Engine" approach. Rather than just showing you where the price is, the script calculates:

  • Relative Momentum: By finding the difference between two different weighting models (Value 1 minus Value 2), it highlights where the market is accelerating or decelerating.
  • Trend Filtering: By providing both a histogram and a line, the indicator allows you to compare short-term momentum against longer-term price dynamics.

Summary for the User

When you see the blue line and red histogram on your screen:

  • The Histogram represents the "immediate" energy of the market based on recent changes.
  • The Line represents a "stabilized" view of the trend based on a much larger pool of historical data.

By observing where these two signals agree or disagree, traders can better identify whether a current price move is a significant trend shift or just temporary market noise.

This indicator calculates and visualizes the differential between two multi-coefficient weighted price models to highlight underlying momentum shifts.

FTLM-STLM_v2

This indicator utilizes four distinct high-order weighted moving average regressions to calculate the divergence between long-term price momentum and short-term volatility shifts.

FTLM-STLM_v1

This indicator calculates two distinct smoothed price series using complex fixed-coefficient linear regressions to identify momentum divergence and trend shifts.

FTLM_001

This indicator calculates two distinct multi-period price momentum signals by applying specific weighted coefficients to historical closing prices and measuring the differential between their respective results.

FTLM_STLM_v1

This indicator utilizes multiple distinct weighted linear regressions over a 90-bar period to calculate price momentum shifts through differential smoothing.

s_ftlm-stlm

This indicator calculates the divergence between two distinct weighted linear regressions by subtracting multiple high-coefficient historical price points to reveal trend momentum.

s_rbci

This indicator calculates the variance between two distinct multi-period linear weighted price averages to identify momentum divergence.

STLM_hist_v2

This indicator utilizes a complex weighted summation of historical closing prices to calculate and visualize momentum shifts through a dual-histogram comparison.

STLM2_v2

This indicator calculates a directional bias by comparing two distinct weighted moving averages of historical closing prices to identify bullish and bearish momentum shifts.

STLM_hist

The indicator calculates the divergence between two distinct linear regression weight models over a 90-period window to identify directional momentum shifts.

STLM2_002

The indicator calculates two distinct weighted moving averages using fixed coefficients to determine momentum direction and intensity via a histogram.
