Master Filter - Trend and Smart Money ZonesOverview
Master Filter combines a proprietary trend engine with the smart-money tools traders actually act on - EMA structure, Fair Value Gaps, Order Blocks and market-structure labels - in a single, clean overlay. Instead of stacking five separate indicators, you get one consistent read of where the trend is and where price is likely to react .
Everything is computed on the current chart timeframe and updates live as new bars form.
What's inside
1. The Master Filter © - trend & signals
A triple-smoothed price baseline (TEMA) is tracked against an adaptive average that follows the highs in an uptrend and the lows in a downtrend. An ATR-based channel (length 365 x multiplier, smoothed) acts as a confirmation filter that aims to suppress false flips during chop. When direction confirms, the script prints a LONG / SHORT marker on the bar. You can optionally plot the high / middle / low channel lines.
2. EMA suite + smoothed mirrors
EMA 100 / 200 / 300 / 365 for trend context, with a shaded zone between the 300 and 365 EMAs. Two optional "mirror" EMAs (a smoothed reflection of the 200 and 365) project the opposite side of price to frame mean-reversion zones.
3. Fair Value Gaps (current timeframe)
Three-bar imbalances are drawn as boxes with a dashed mid-line and tagged with the chart timeframe. Live gaps extend to the current bar and are removed automatically once price trades back through them (mitigation). A "max visible" cap keeps only the most recent gaps.
4. Order Blocks (current timeframe)
SMC-style order blocks are detected on structure breaks (price closing through the last swing high/low). The OB candle is selected within a bounded search window, with a volatility filter so an oversized, high-range bar isn't mistaken for the block. Each OB is drawn as a box plus dashed mid-line, kept per direction up to a configurable limit, and dropped on a strict break. A "max pivot age" setting skips stale blocks far from current price during strong trends.
5. Market structure - HH / HL / LH / LL
Swing pivots are labelled as Higher High / Higher Low / Lower High / Lower Low (teal for higher, orange for lower) so structure shifts are visible at a glance.
How to use
Read the trend from the LONG/SHORT markers and EMA stack; trade with it.
Use FVG and Order Block zones as areas to look for entries, partial exits or invalidation - not as automatic buy/sell signals.
Confirm with HH/HL/LH/LL: continuation favours trend-aligned zones; a structure break warns of a possible shift.
Settings
Grouped by section - Main trend (length, multiplier, channel filter, plot channel), Moving Average (EMA lengths, mirrors, smoothing), Fair Value Gaps (show, max visible, colours), Order Blocks (show, max per side, search/structure length, max pivot age, colours), and HH/HL/LH/LL (show, swing length, lookback).
Alerts
Change of the trend - fires when the Master Filter direction flips.
Notes
This indicator is a decision-support tool, not a signal-for-hire system. It does not place orders and past behaviour does not guarantee future results. Always combine it with your own risk management.
