How to install FRK Levels and read every feature · Updated October 13, 2026 · Illustrations use sample data

Getting started

FRK Levels draws FRK levels, GEX support and resistance, the expected move, volume bubbles and a delta profile on your own TradingView chart. Setup takes about two minutes.

Subscribe at frkcharts.com/levels. After checkout you choose your FRK Levels username and password.
Download the extension from the Install tab on your account page and unzip it.
Install in Chrome (or Edge or Brave): open chrome://extensions, turn on Developer mode, click Load unpacked and pick the unzipped folder.
Sign in: click the FRK Levels icon in the toolbar and enter your username and password. Allow access to api.frkcharts.com when Chrome asks.
Open a chart on tradingview.com. The levels appear on their own.

The status panel in the bottom-left corner of the chart tells you what the extension is doing:

Dot	Text	Meaning
Green	Live	Levels and GEX are current
Amber	Connecting to feed	Loading; wait a few seconds
Amber	Live · GEX offline	Levels are current; GEX is temporarily unavailable
Red	Sign in from the FRK Levels extension icon	You are signed out
Red	Feed expired	The connection dropped; it reconnects on its own

FRK levels

FRK draws the same ladder of levels on three timeframes, each in its own column to the right of price. Each frame recalculates on its own, driven by time, price and volatility rather than a fixed schedule, so the spacing widens in fast markets and tightens in quiet ones.

Frame	Badge	Use it for
Scalp	S	The next trade, intraday swings
Daily	D	Swings over a couple of days
Weekly	W	The multi-week trend

Each frame has the same levels, top to bottom:

Label	Level	Role
EH	Extension High	Outer edge of the range
R3, R2, R1	Resistance 3–1	Sell zone; R3 is the strongest
MS	Mid-S	Halfway between R1 and R
R	Resistance	Upper reaction level
BT	Balance Top	Top of the balance zone
PP	Pivot Point	Centre of balance
BB	Balance Bottom	Bottom of the balance zone
S	Support	Lower reaction level
MB	Mid-B	Halfway between S and S1
S1, S2, S3	Support 1–3	Buy zone; S3 is the strongest
EL	Extension Low	Outer edge of the range

Thin grey mid lines sit halfway between neighbouring levels. Hide them per frame with the Mids checkbox; Scalp mids start hidden. Scalp also hides its labels to keep the column narrow.

Zones

Each frame shades three kinds of zone. Buy the green zone, sell the red zone, and expect two-way trade in the blue one.

Zone	Colour	Between	How to use it
Sell	Red	R3–R2 and R2–R1	Look for shorts; price is stretched to the upside
Balance	Blue	BT–BB	Fair value; expect chop and mean reversion
Buy	Green	S1–S2 and S2–S3	Look for longs; price is stretched to the downside

Overlapping zones are the strongest signal. When the Scalp buy zone sits inside the Daily buy zone, a short-term entry lines up with the bigger swing. Daily inside Weekly does the same for the larger move. The more frames agree, the stronger the level.

Views

The View menu in the popup controls how much is drawn. Start with All Levels; switch to Simple when the chart feels busy.

View	Shows	Best for
All Levels	Every level, mid and zone of each frame you have switched on	Full picture, planning the day
Simple	Only the levels where GEX support or resistance sits	A clean chart while trading
Zones	The Scalp levels with GEX, each linked to the nearest Daily level	Seeing where a scalp level lines up with the swing
All + Zones	All Levels plus the Scalp-to-Daily links	Both at once

The same chart in each view: All Levels, Simple, Zones and All + Zones.

A frame you switch off still draws any level where GEX support or resistance sits, so you never lose a wall.

GEX support and resistance

Live options gamma (GEX) marks the strikes where dealers hedge hardest. FRK Levels shows live GEX support and resistance highlighted on your FRK levels, so you see which levels have real options interest behind them.

Look	Meaning
Thick hollow orange line	GEX resistance (call wall)
Thick hollow purple line	GEX support (put wall)
Glow	The primary support or resistance; the second ones draw without the glow
Small triangle at the left end	The king: the single largest gamma strike

Thick hollow orange and purple lines on FRK levels marking GEX resistance and support, with a small triangle marking the king — Orange GEX resistance with the king triangle on Scalp R2, and purple GEX support on Daily S1.

The lines are hollow so you can still read candles through them. GEX updates every few seconds during market hours; when it can't update, the status panel shows Live · GEX offline and the highlights clear.

Expected Move

The Expected Move lines show how far the options market expects price to travel from yesterday's close. They come from the at-the-money straddle priced at the 4:00 pm ET close and stay fixed for the whole session.

Line	Distance from the prior close	Rough meaning
+1σ	+ 1.25 × straddle	One standard deviation up; about 68% of sessions close inside ±1σ
EM Hi	+ straddle	The average day's move up
EM Lo	− straddle	The average day's move down
−1σ	− 1.25 × straddle	One standard deviation down

Dashed purple +1σ, EM Hi, EM Lo and −1σ lines across an NQ chart — EM Hi and EM Lo at the prior close ± the straddle; +1σ and −1σ outside them.

All four are dashed purple lines across the chart, labelled at the left. Price reaching EM Hi or EM Lo means the day has already made a full average move; ±1σ marks an extended day. The percentages assume a normal distribution, and real markets have fatter tails.

On NQ and ES the lines use the futures close; on NDX and SPX they use the index close, so they sit at the right price on both. They show while GEX is live. Turn them off with Expected Move (HI/LO, ±1σ) in the popup.

Volume bubbles

A volume bubble marks a burst of large trading: trades at the same price and side, each within 1 second of the last, added together. Big bubbles at a level show where larger traders stepped in.

Look	Meaning
Teal ring	Buyers lifted the offer
Red ring	Sellers hit the bid
Grey ring	Side unknown
Ring size and number	Total contracts; bigger ring, bigger trade

Teal buyer bubbles at a session low in the Daily buy zone and a red seller bubble at the latest high — Buyers (teal) stepping in at the low inside the Daily buy zone; sellers (red) at the push into resistance.

Each bubble sits on the bar where the burst started, at its price. Only the top 10% of bursts this session show, and never fewer than 20 contracts on NQ or 100 on ES. A teal bubble in a buy zone, or a red one in a sell zone, confirms the level is being defended.

Bubbles show on NQ, MNQ, ES and MES futures charts only. Turn them off with Volume bubbles in the popup.

Delta profile

The delta profile shows, at each price, whether buyers or sellers were more aggressive today. It draws as horizontal bars along the right edge of the chart, just left of the price scale.

Blue bar: more buying than selling at that price.
Red bar: more selling than buying.
Bar length: the size of the imbalance; the largest row is 120 pixels long.

Blue rows: more buying at that price. Red rows: more selling.

It covers the full session from the 6:00 pm ET open and updates about every 5 seconds. A long red bar under a sell zone shows sellers defending it; a run of blue bars through a level shows buyers absorbing supply.

The delta profile shows on NQ, MNQ, ES and MES futures charts only. Turn it off with Delta profile in the popup.
