Filter Reference
Complete reference guide for all 65+ scanner filters in Scanz. Includes filter categories, syntax patterns, comparison operators, and practical examples for building powerful stock scans.
Quick Start
To add a filter to your scan:
- Click + Filter in the filter panel
- Select a category (Price, Change, Liquidity, etc.)
- Choose a specific filter from the submenu

Intraday Timeframes
Scanz supports extensive intraday timeframes for charts, filters, and technical indicators. This is one of our key strengths for day traders.
Candle/Chart Intervals:

| 30 Minutes | MIN_30 | Intraday support/resistance |
| 1 Hour | HOUR_1 | Hourly trends, swing trading |
| Daily | DAY_1 | Swing trading, position trading |
Intraday Change Intervals: Measure price/volume changes over specific minute intervals: 1, 2, 3, 4, 5, 10, 15, 30, 60, 90, 120 minutes.
Multi-Day Change Intervals: Track changes over multiple days: 2, 3, 4, 5, 10, 15, 20, 30, 45 days.
Weekly/Monthly/Yearly:
- Week to Date (WTD), 1-52 weeks
- Month to Date (MTD), 1-12 months
- Year to Date (YTD), 1 year (260 trading days)
Maximum Historical Lookback: 260 periods
Moving Average Timeframes
Moving averages (SMA, EMA) can be calculated on any candle interval:
- 1-minute MA: Fast-moving, great for scalping setups
- 5-minute MA: Standard day trading timeframe
- 15-minute MA: Smoother intraday trends
- Daily MA: Traditional swing/position trading
Moving Average Crossover Examples:
50/200 SMA cross on 5-minute charts:
SMA 50 | 5min greater than SMA 200 | 5min
9/20 EMA cross on 1-minute charts:
EMA 9 | 1min greater than EMA 20 | 1min
Golden Cross on daily charts:
SMA 50 | Daily greater than SMA 200 | Daily
Comparison Operators
| Operator | Description | Example |
|---|---|---|
| Greater Than | Value exceeds threshold | Last Price greater than 10 |
| Less Than | Value below threshold | Last Price less than 100 |
| Equal To | Exact match | % Change equal to 0 |
| Greater Than Or Equal To | Value at or above threshold | Volume greater than or equal to 100000 |
| Less Than Or Equal To | Value at or below threshold | RSI less than or equal to 30 |
| Between | Value within range | Last Price between 5 and 50 |
Relative Comparisons (By Modifier)
When comparing one value to another (e.g., current volume vs. previous volume), you can enable the “by” checkbox to specify how much greater or less the value should be. This unlocks three comparison modes:
| Mode | Description | Example |
|---|---|---|
| Value | Absolute difference in the same units | Volume | RH greater than Volume | RH[-1] ☑ by more than 100000 Value |
| Percent | Percentage difference | Last Price greater than Open ☑ by more than 5 Percent |
| Times | Multiplier comparison | Volume | RH greater than Volume | RH[-1] ☑ by more than 3 Times |
How to use:
- Set up a filter comparing two values (e.g.,
Volume | RH greater than or equal to Volume | RH[-1]) - Check the “by” checkbox that appears
- Enter your threshold value
- Select Value, Percent, or Times from the dropdown
Practical Examples:
Volume surge (3x previous candle):
Volume | RH greater than or equal to Volume | RH[-1] ☑ by more than 3 Times
Price broke above VWAP by at least 2%:
Last Price greater than VWAP ☑ by more than 2 Percent
Price within $0.50 of day high:
Last Price greater than or equal to High ☑ by less than 0.50 Value

Tips for Power Users
- Start broad, then narrow - Begin with fewer filters and add more to refine results
- Use relative metrics - Relative Volume is more useful than absolute Volume for finding unusual activity
- Combine technical and fundamental - Price action with float/short data creates powerful setups
- Save successful scans - Build a library of scans for different market conditions
- Monitor filter counts - Too many filters may return zero results; too few returns noise
