Best Free Order Block Indicators for TradingView: Top Tools Compared
Free order block indicators on TradingView mark zones defined by programmed price and volume rules. They do not directly observe an institution's unfilled orders. The useful comparison is how each script defines a zone, when it confirms that zone, what invalidates it and whether its historical display matches information available in real time.
Flux Charts, LuxAlgo and TradingFinder publish identifiable free tools with different calculations. The descriptions below follow those specific publications. There is no measured performance ranking or claim that one produced superior trading results.
What an order block means on a chart
“Order block” is a technical-analysis label rather than a standardized exchange data field. Some scripts identify a candle preceding a structural break; others use volume pivots. Drawing a box around either pattern does not reveal the owners of past trades or prove that resting orders remain at that price.
A strong move after a candle is observable. The claim that an institution caused it and will defend that area later is an additional hypothesis. Volume can quantify activity in the selected feed, but does not identify the participants. A fair value gap is a separate chart pattern and is not a mandatory feature of every order-block algorithm.
Before comparing scripts, write down four definitions:
| Definition | What to record |
|---|---|
| Formation | Which price, swing, volume or structure conditions create the zone? |
| Confirmation | Which completed bar first makes the condition knowable? |
| Boundaries | Are the box edges full candle high/low, body, midpoint or a refined range? |
| Invalidation | Does a wick, close, touch or another rule retire the zone? |
“Mitigated” and “unmitigated” refer to these chosen rules. They are not measurements of how many institutional orders have been filled.

Order Blocks | Flux Charts: chart zones with a volume display
Order Blocks | Flux Charts is an open-source chart indicator by fluxchart. Its documented controls include bullish/bearish zones, optional volumetric information, historic-zone visibility, swing length, zone count and Wick/Close invalidation.
Its displayed volume split is derived from selected candle volumes. The publisher describes grouping the last two bars versus an older bar, with the interpretation reversed for bullish and bearish blocks. That is not a direct measurement of buyer-initiated and seller-initiated transactions inside an institution's order book.
A shorter swing length can identify smaller structures. It does not establish that length 5 is best on daily charts. Compare candidate settings on the same symbol, session and interval, and keep the first time each zone became available.
Order Blocks Screener | Flux Charts: a separate five-ticker tool
The Order Blocks Screener is a different publication, not a feature bundled into every Flux order-block indicator. Its page documents up to five selected tickers with individual timeframes, latest-zone status, retest counts and the script's volume estimates.
That makes it relevant when the task is monitoring a small predefined list. It is not a scan of every stock or currency pair. Check ticker exchange prefixes and feed availability, and confirm whether a higher-timeframe value is final before treating a status change as actionable.
The screener's retest count follows its own definition. It is not a count of institutions defending a price or proof that another retest has a higher probability of success.
Order Block Detector [LuxAlgo]: confirmed volume pivots
Order Block Detector [LuxAlgo] is an open-source volume-pivot detector. It supports bullish/bearish block display counts, Wick or Close mitigation, and alerts for creation and mitigation.
Its published description explicitly states that confirming a volume peak requires subsequent bars equal to the Volume Pivot Length. Zones are therefore shown retrospectively. A box anchored several bars earlier was not necessarily visible or tradable on its anchor candle.
For this implementation, bullish zones span the low to the median price and bearish zones the median to the high. These are specific construction rules, not a universal definition of an order block.
Do not attribute BOS/MSS overlays, Fibonacci tools or every feature of LuxAlgo's other suites to this individual detector. Also, “no volume data” would be misleading: volume peaks are central to detection, even though its display differs from Flux's volume breakdown.
Order Blocks Finder [TradingFinder]: structure and configurable zones
The exact Order Blocks Finder [TradingFinder] Major OB | Supply and Demand publication identifies blocks after structure breaks and provides zone refinement, colors, optional static support/resistance levels and touch alerts.
The publisher documents alert frequency, time-zone display and custom long/short messages. These configure how an event is presented; they do not change whether the underlying condition has a trading advantage.
Review the actual refinement setting before interpreting a narrower or wider box. A smaller stop distance can increase position size under a fixed risk budget, but it can also change stop frequency. Neither range automatically improves realized reward-to-risk.
Candlestick tools provide a separate condition
A candlestick-pattern indicator can label an engulfing bar or another pattern near a manually selected zone. It is not an order-block detector merely because you combine the two. Specify the exact pattern and the bar on which it confirms; do not treat an unspecified “All Candlestick Patterns” script as a tested fourth order-block product.
Configure invalidation correctly
In the documented Wick/Close distinction, a bullish zone can be invalidated when the low crosses its lower boundary under a wick rule, while a close rule waits for the close to cross the relevant boundary. For a bearish zone, the corresponding upper boundary matters.
Under those conditions, wick invalidation is generally more sensitive to an intrabar excursion. It does not inherently “give the trade more room.” A wick can cross a boundary and recover while the close remains within it. Exact equality and real-time evaluation still depend on the script.
Start with the author's defaults to understand behavior, then change one setting at a time. Save the symbol, timeframe, session, version, volume feed and settings. Reducing the number of visible boxes changes chart clutter, not the probability that the remaining zones will hold.
Evaluate confirmation timing and repainting
TradingView's repainting documentation explains why historical and real-time outputs can differ. For order-block tools, three checks are especially useful:
- Anchor versus confirmation: Record both the original candle and the later confirmation bar. Entries must not precede confirmation.
- Historical zone removal: A chart showing only surviving zones omits failures. Preserve invalidated zones or log all detections when evaluating results.
- Higher-timeframe inputs: Determine whether the current higher-timeframe bar is still developing. A lower-timeframe chart cannot make that unfinished value final.
Replay can help inspect these behaviors, but a polished historical chart is not a strategy backtest. Reload the chart and compare what remains with a prospective log. Closed-bar alerts reduce some intrabar changes but do not remove every source of revision or lookahead.
Turn the zone into a testable rule
For a hypothetical long setup, define a confirmed bullish zone, the permitted retest window and one explicit entry condition. For example, the first completed retest bar must close above a chosen zone boundary, with an order submitted only afterward. This is an example to evaluate, not a recommendation or measured profitable setup.
Specify invalidation, stop, target, order type and maximum holding time before examining outcomes. A limit order touching on a historical candle is not proof of a fill, and a stop cannot guarantee the intended exit through a gap.
Position size should follow the contract's value and a chosen risk budget. For a hypothetical stock trade with $100 budgeted risk and a $2 entry-to-stop distance, 50 shares would expose $100 before fees and slippage. Futures require their point value, and options require a separate premium and contract model. This is not a universal account-risk percentage.
Add filters only when they answer a separate question. An EMA, a structure break and a zone can all be derived from the same price movement. More agreeing labels do not necessarily supply independent evidence. Evaluate the complete rule on later data and include every failure, costs and drawdowns.
Customization and platform limits
Open-source publications let readers inspect their logic subject to licensing and TradingView publication rules. Paid access does not establish higher accuracy, and free access does not mean all chart, alert or market-data limits disappear. Consult the current TradingView plan comparison for those limits.
Pineify can support Pine development and configuration of supported indicators. A particular custom order-block detection or multi-symbol scanner may require code beyond the visual editor's available controls. Define the desired algorithm first, then verify the generated source, confirmation timing and platform resource limits. Syntax success alone is not evidence of a profitable strategy.
Frequently asked questions
Which free order block indicator should I inspect first?
Choose by task. Flux's chart indicator provides zones and candle-volume estimates; its separate screener monitors up to five selected tickers. LuxAlgo uses confirmed volume pivots, while TradingFinder offers structure-based zones and touch alerts. No measured winner is established here.
Do order blocks reveal unfilled institutional orders?
Not from chart candles alone. They are zones inferred by an algorithm. The remaining orders, identities and motives of participants are not established by a box or a volume label.
Does Wick invalidation give a zone more room than Close?
Not under the usual boundary-crossing definition. A wick can cross a boundary while the close returns inside, so the wick rule can invalidate earlier. Check the exact script's logic.
Are higher-timeframe blocks always more reliable?
No universal reliability ranking is established. Higher intervals change the sampling, zone width and confirmation delay. Test the intended rule on the relevant instrument and include realistic execution costs.
Can I trade at the candle where a historical box begins?
Only if the zone was knowable then. Pivot and structure confirmation can occur later. Use the actual detection time rather than the retrospectively drawn anchor when evaluating an entry.
