Liquidity Raids

已更新

A raid/sweep occurs when price takes out a previous high/low i.e., price sweeps a level, grabs liquidity and reverses. When this occurs in higher time frames (HTF) like 1h, 4h, daily, etc., there's a greater chance for minor/major reversal/pullback in lower time frames (LTF). For clarification, this is not my concept - ICT students and price action traders call it "liquidity grab", some call it "stop hunt", some call it "evil market maker", etc. There are some indicators which plot this already, but none of them have what I need (multi-timeframe support and filtering swing points).

Typically, we look for raids in HTF, which is set to the timeframe parameter of the indicator. Then, we go into LTF for execution, and we'll see HTF raids plotted there (which greatly eases backtesting and execution). We can also check "filter swing points" to only show raids of swing points (3-candle pattern).

The above chart shows this indicator in action (1m chart showing raids from 15m with swing point filter enabled).

This indicator also supports setting alerts for raids.

Alert only on HTF bar close

版本注释

Fix HTF alert

版本注释

Allow only 1 or 2 alerts per HTF bar close

版本注释

Major update

Adds support for raids into significant levels (Monday range, previous daily range, previous weekly range)
Can display significant levels currently being monitored
Also has the option to exclude normal raids (if you're only interested in level raids) or disable level raids (so that you can go back to the first version of the indicator)
Alerts for raids into significant levels

NOTE: The timeframe defined will be used for all kinds of raids.

Could be buggy, but will fix bugs as I find :)

版本注释

Major update: Session raids

Support for raids on previous session highs and lows (Asia, London, NY, Sydney - all configurable in NY local time)
Shows session ranges as boxes (with names), but can also be disabled if you have other indicators to do it
Adds 5-bar pattern for swing points
Also adds monthly highs and lows to the list of supported significant levels

版本注释

Auto-adjust DST so that session ranges don't get affected

版本注释

Updated default sessions to KZ (session names can now be configured)
Bug on Monday range being extended on HTF (like daily) because of default line length (removed it entirely)
Fixed wrong calculation of Monday range in legacy markets because of pine script bug in dayofweek indexes
Optional labels for raids on levels

版本注释

Minor update: Make sessions DST friendly (allow specifying UTC/London/NY times)

版本注释

Use session names on alerts

版本注释

Remove raid lines beyond a specified number

版本注释

Removed capping for maximum lookback bars
Supports specifying minimum pips required for raids
Fixed buggy raids on equal highs/lows and 5-bar swing fractal

版本注释

Add filter to ignore raids outside of sessions and fix bug in repainting same raid multiple times

版本注释

Support limiting maximum session boxes displayed

版本注释

Support changing label sizes

版本注释

Shorthand labels are supported for levels and they also optionally include prices.

版本注释

Support displaying pips of raids and drawing session range lines (as an alternative to boxes)

版本注释

Choch support

Added support for detecting choch based on pivots (in any higher timeframe relative to the current chart). You'll need to experiment with pivot lengths though.
Chochs can be filtered to the first one occurring immediately after a raid.
Alerts can be configured to trigger on either raids, or after first choch following raid, or both.

版本注释

Fixed bug when max. raids/chochs are limited to one.

版本注释

Workaround for pinescript causing intermittent issues with drawing raid lines when changing timeframes.

版本注释

- Got rid of pivot-based lookup for chochs. Instead going for swing highs/lows and market structure shifts. This is what works for me and what I find useful (not planning to go back to pivots again).
- Also fixed lookback errors for higher values. We can now go for up to 5000 candles and sometimes more (which will take time, but raids will show up).
- Choch detection is activated whenever a swing point of interest is taken out (which includes candle closes as well, for which raids are not marked, however filters are taken into account for such swing points) and only chochs following raids are displayed (it complicates the code for me otherwise).

版本注释

Don't display raid or choch when timeframe is higher than configured

版本注释

Minor fixes
Option for disabling raids, opposite choch,
Display lines for daily, monthly, weekly and custom time (thinking about adding raids of open lines somehow)
Swing points for chochs and raids are considered when they have 2 equal highs or lows in them (flexible 4-candle pattern instead of fixed 3-candles)

版本注释

Support customizing open lines and add 3 custom opens

版本注释

Generalized padding for levels and added line style for opens and levels

版本注释

Enable/disable opens based on checkbox

版本注释

Alert once per bar close

版本注释

Fixed some bugs and added open line history for one custom open (useful for true day open)

版本注释

Support plotting and alerting swing formation
