Key Levels
The structural map of the FLB ecosystem. Auto-plots Asia, London, Previous Day, Pre-Market, Opening Range, Opening Candle, plus the full HTF stack — 4H, 7H, Weekly, Monthly, Quarterly, and Yearly opens, highs, lows, and mids — into a single layer with smart label merging.
The structural map of the auction.
Key Levels draws the price levels where institutional participation has historically been heaviest — session highs and lows, previous day extremes, pre-market bases, opening ranges, the first 30 minutes of regular trading, and the higher-timeframe opens, highs, lows, and mids that institutional desks watch most closely. These are the places the crowd shows up.
Key Levels does not tell you to trade. It tells you where to pay attention. Whether you fade the level or trade through it is decided by the rest of your FLB stack — your zones, your Surge confluence, your Trade Shield state. The levels are the map. The ecosystem makes the call.
Module 1 — Key Levels. Asia, London, and Previous Day high/low with full styling control and touch alerts.
Module 2 — Session Ranges. Pre-Market Range (08:00–09:00) and Opening Range (09:30–10:30) as persistent reference rectangles.
Module 3 — OC Levels. Opening Candle box with Open/Close lines extending right. Configurable window.
Module 4 — HTF Levels. 4H, 7H, Weekly, Monthly, Quarterly, and Yearly opens, prev highs/lows, and prev mids. Each level individually toggleable.
Reaction comes in two flavors
Levels are not magic. They're the places where large size tends to transact, which means they're where price tends to react. Both reactions happen. Neither is more 'correct.' The question is what does the rest of your stack tell you.
The break
Price breaks the level and accelerates through it — the participants defending it ran out of inventory. Trade with the break.
The hold
Price touches the level and reverses — the participants defending it had more size than the move had conviction. Trade with the rejection.
No confluence
Price reaches the level with no Surge alignment, conflicting FLB zones, or Trade Shield warning. The honest answer is no trade.
The FLB way. Key Levels tells you where. FLB zones tell you value. Surge tells you momentum. Trade Shield tells you whether you're fit to trade. No single tool makes the trade — the confluence does.
Every level explained
All times America/New_York. Sessions reflect the futures trading day (18:00 ET start). Turn individual levels on or off as needed for your style.
Asia Session H/L
The overnight auction. Marks the range established by Asian-hours traders. Breaks above Asia High or below Asia Low during US hours often signal directional continuation. Rejections produce the cleanest reversals.
London Session H/L
The European auction. Often the most aggressive non-US session. Wide London range = active US session. Tight London range = compressed US session that breaks late.
Previous Day H/L
Yesterday's extremes — the most-watched reference levels on any chart. Breaks often accelerate as stops get run. Rejections produce the highest R:R reversals because of accumulated liquidity.
Pre-Market Range
The hour before regular trading. Marks where pre-market participants set their bias before the cash open. Pre-market high breaks often continue. Pre-market low breaks often fail into reversal.
Opening Range
The first hour of RTH. The most structurally important range of the day for NQ/MNQ. Breakouts set the session's directional bias. Returns inside the range after a breakout often signal failed breakout reversal setups.
Opening Candle (OC)
The first 30 minutes drawn as a colored box showing net direction. Open and Close price lines extend right as reference levels. The OC's high, low, open, and close are all active magnets for the rest of the day.
4H Levels
Open, previous high/low, and previous mid for the running 4-hour candle. Heavy intraday reaction zones — institutional desks use 4H opens as bias dividers. Strong magnet on intraday pullbacks.
7H Levels
Custom 7-hour interval that splits the futures trading day cleanly. Open, prev H/L, and prev mid. Often picks up institutional reference points that standard 4H and Daily miss.
Weekly Levels
The most defended of the HTF set. Weekly Open is one of the strongest pinning magnets in the market — Mondays especially. Default-on with the Open enabled, prev H/L and prev Mid available.
Monthly Levels
The big-picture bias divider. Monthly Open is the line institutional desks watch for the entire month. Default-on with the Open enabled, prev H/L and prev Mid available for additional context.
Quarterly Levels
Long-horizon reference. Heaviest reaction in the first week of a new quarter when desks are repositioning. Open, prev H/L, and prev mid all available — disabled by default to keep charts clean.
Yearly Levels
The widest reference frame. Uses the current running year H/L since the year is in progress — not last year's closed range. Yearly Open often signals the entire year's directional bias.
Run them together — or individually
Each module has its own on/off toggle at the top of settings. Most Hunters Club members run all four simultaneously for the complete map.
Key Levels
Asia, London, Previous Day high/low. Full styling control plus touch alerts.
Always on unless you have a specific reason to disable.
Session Ranges
Pre-Market (08:00–09:00) and Opening Range (09:30–10:30) as persistent rectangles.
Every US session. Disable on non-US futures or if you exclusively trade overnight.
OC Levels
Opening Candle box with Open/Close lines extending right. Configurable window — 09:30–09:45 for tight scalping, 09:30–10:00 for full half-hour read.
Recommended for all US session traders. The OC close is one of the highest-reacting levels of the entire day.
HTF Levels
4H, 7H, Weekly, Monthly, Quarterly, and Yearly opens, previous highs/lows, and previous mids. Each level individually toggleable.
Default-on with Weekly Open and Monthly Open only. Add 4H, 7H, Quarterly, or Yearly individually as your strategy requires.
Width + position predict the US session
Asia and London Trend Lines are the most overlooked tools on the panel. They aren't reaction zones — they're a forecast for what kind of US session you're about to trade.
Read the width
Wide: range-bound — fade the extremes, breakouts often fail.
Narrow: compression — expect a decisive breakout, avoid fading.
Average: no edge from width alone — read position next.
Read the position
Above the high: bullish bias for the day.
Below the low: bearish bias for the day.
Fades against this position have a much lower success rate.
Combine both
Wide + above: chop with upside bias. Long fades at lows.
Narrow + above: upside breakout — lean long, trail stops.
Wide + inside: pure chop — fade both extremes.
Narrow + inside: waiting for the break — let price choose.
Comparing the two trend lines. If Asia and London agree on width and position, the overnight has unified direction — cleanest setup for the US. If they disagree, the open is where that resolves. Expect a volatile first hour.
Confluence detection, automated
When two or more levels land on the same price — Asia Low and Prev Day Low both at 28,500, the Weekly Open coinciding with Prev 4H High — that's confluence. The places institutions actually watch hardest. The merge system catches these automatically.
Right-edge labels
Every level draws a label that floats at the right edge of the chart like a price tag. Labels never sit on top of price action — they live in the empty space past the current bar, out of the way of your candles.
Format options: Full Name, Compact, with or without price. Style: Text Only or Tag (filled pill). Configurable offset.
Tolerance matching
Two prices rarely match exactly. Merge uses a percentage tolerance to decide what counts as the same price. Default 0.01% — at NQ 28,000 that's a 2.8-point window.
Wide enough to catch functionally-equivalent levels, tight enough to avoid false merges. Adjustable per chart.
Combined labels
When merge fires, you see one line and one label that reads Asia Low / Prev Day Low instead of stacked duplicates. Cross-module — Key Levels merge with HTF.
Multi-timeframe agreement at a single price is the structure institutional flow defends most aggressively.
Leave merge ON. When the chart automatically combines a level into a confluence label, that's exactly the spot you should be paying attention to. The merge is the indicator's way of saying "look here first."
Module-level controls
Four module toggles plus per-level visibility. Every line, label, and color is configurable.
Module Toggles
| Enable Key Levels On | Module 1 master toggle. Asia, London, Previous Day high/low. |

Module 4 — HTF Levels
| 4H Group Off | Toggle Open, Previous H/L, and Previous Mid independently. Each has its own color and width. |
| 7H Group Off | Custom 7-hour interval. Same per-level toggles as 4H. |
| Weekly Group Open On | Open enabled by default. Toggle Prev H/L and Prev Mid as needed. |
| Monthly Group Open On | Open enabled by default. Toggle Prev H/L and Prev Mid as needed. |

How traders misuse Key Levels
The single most common mistake is trading the level in isolation. Levels are not signals.
Trading the level in isolation
Price touches Prev Day High, trader takes a short, gets run over. The level was doing its job — acting as a reaction zone. Reaction includes continuation.
Ignoring FLB zone context
Fading Prev Day High while price is still inside an upper FLB zone is fighting the structural bias of the day. Without a ceiling, a fade is a donation.
Fading without Surge divergence
Levels that fade cleanly almost always have Surge divergence at the touch. If Surge is still pushing in the trend direction, the level is about to break, not hold.
Overriding Trade Shield to 'just take this one'
Every trader has felt the urge to override tilt warnings for a 'perfect' setup. Those overrides turn 10% drawdowns into 25% drawdowns.
Taking every touch
Price can tag the same level three or four times in a session. You don't trade all four. You trade the one with confluence.
Confusing reference with reaction
Trend lines, OC Open/Close extensions, and pre-market lines are reference levels — context, not active reaction zones. Don't treat them like Prev Day High.
Letting the chart get too busy
Every module enabled with every HTF level on every chart looks impressive and trades poorly. Stick to the defaults — Weekly Open and Monthly Open from HTF, Asia/London/Prev Day from Key Levels — and add others only when you have a specific reason.
Treating trend lines as reaction zones
Trend lines are forecasts of session character — width and position predict behavior. They aren't levels to fade or break. Read them, don't trade them.
Frequently asked
The Asia and London windows can be drawn on supported symbols using their configured Eastern Time schedules. Pre-Market and Opening Candle windows are designed around the New York cash session and may not describe another venue's auction. Higher-timeframe levels depend on the chart's available bars and session data.
Asia session ends at 00:00 ET. The high/low lines persist forward through the trading day. If you don't see them, check (1) Asia module is enabled and (2) the chart has loaded enough history to capture overnight bars.
Yes. Configure OC Start Time and OC End Time in settings. 09:30–09:45 gives a tight scalp window, 09:30–10:00 is the default 30-minute OC, 09:30–10:30 covers the full Opening Range.
Session high and low mark the observed extremes inside the configured window. Trend lines are diagonal references drawn from the session's opening point to its ending point. They summarize the completed path; they do not forecast the upcoming US session.
Three options. Once Per Bar Close (default, quietest) fires when a bar closes touching the level. Once Per Bar fires on the first touch within a bar — faster, useful intraday. Every Tick fires continuously while price is at the level — loudest, only useful for very narrow setups. Set in TradingView's alert dialog.
When two or more levels land within tolerance of the same price — for example Asia Low and Prev Day Low both at 28,500 — the labels combine into one ("Asia Low / Prev Day Low") and the duplicate lines are hidden. Cross-module: Key Levels merge with HTF. Default tolerance is 0.01%, adjustable per chart. The merge fires automatically; you don't configure it per level.
The yearly module is designed to show the developing current-year high and low. Shorter higher-timeframe modules use the previous completed period. This product-design choice separates developing annual context from completed shorter-period references; it does not imply that prior-year levels are irrelevant.
Show Historical Data retains prior Opening Candle references for review. Leave it on when historical comparison is part of the workflow, or turn it off when the additional marks obscure current context. The display choice does not improve signal probability by itself.
There is no universally highest-priority alert. Start with the levels defined in your written process, such as prior-day high or low and weekly or monthly opens, then test alert frequency in replay or simulation. A displayed level is context, not a prediction of reaction probability.
Versions are available for TradingView and NinjaTrader 8. Both cover the core session and higher-timeframe reference workflow, but platform data, interfaces, calculations, alert behavior, and available settings can differ. Review the documentation for the edition you use and validate it on your own chart configuration.
