How to use a crypto screener to filter thousands of coins

Published · by Hunt4Coin

A crypto screener is a tool that checks many coins at once against conditions you choose, such as "RSI below 30 on the 4-hour chart" or "volume twice its usual level", and shows only the coins that match, so you study a short list instead of thousands of charts.

Why use a screener

There are thousands of coins and nobody can open every chart. A screener does the first pass for you: it turns a vague idea ("something oversold in an uptrend") into exact rules and returns a list you can sort and check by hand. It doesn't tell you what to buy; it tells you where to look.

Step 1: start from a question, not a coin

Write your idea as one sentence first. For example:

  • Which large coins have fallen hard and look stretched to the downside? → RSI condition.
  • Which coins just turned from a downtrend to an uptrend? → Supertrend flip or a fresh MACD cross.
  • Where is unusual activity today? → volume compared with its average.
  • Which coins are quiet and might be about to move? → Bollinger squeeze (narrow band width).

Step 2: choose the timeframe

The same coin can look oversold on the 15-minute chart and perfectly normal on the daily chart. Pick the timeframe that matches how long you plan to hold:

  • 15m and 1h: short-term moves, more noise and more false signals.
  • 4h: a middle ground many swing traders use.
  • 1d: the bigger trend; fewer signals, but each one covers a larger move.

A common workflow is to screen on one timeframe and confirm on the next one up.

Step 3: combine two or three conditions

One condition returns too many coins; ten return none. Two or three that check different things work best:

  1. A trend filter: price above the EMA 200, or Supertrend pointing up.
  2. A momentum or timing trigger: RSI crossing back above 30, or the MACD histogram turning positive in the last few bars.
  3. A participation check: volume above its 20-bar average.

Step 4: sort, then open the charts

Sort the results by the column that matters most for your idea (for example, bars since the MACD cross, so the freshest crosses come first). Then open each coin's candle chart and check what the numbers can't show: nearby support and resistance, news, and whether the move already happened.

Step 5: test the rule before trusting it

If a scan keeps finding coins you like, turn it into a rule and backtest it with fees. Many screens that look good on a few charts lose money once you count every trade and its costs. Then practise it with pretend money before using real money.

Common mistakes

  • Treating the list as a buy list. A match only means the numbers fit your rule.
  • Mixing timeframes by accident, such as an RSI on the 15-minute chart with a trend filter meant for the daily.
  • Stacking similar indicators (RSI, Stoch RSI and another oscillator) that all say the same thing.
  • Ignoring liquidity: thin coins can match a scan and still be hard to trade at a fair price.
  • Changing the rule after every result until it fits the past perfectly; it usually stops working on new data.

Try it free

  1. Open the free Hunt4Coin scanner (what it covers): it checks the top 100 coins by market cap on the 15-minute, 1-hour, 4-hour and daily charts, with RSI, Stoch RSI, MACD histogram and bars since the cross, distance from the EMA 200, golden and death crosses, Bollinger %B and band width, Supertrend, ADX, volume versus its 20-bar average and ATR.
  2. Start with a ready-made scan (oversold RSI, fresh MACD cross, Supertrend flip, volume spike, Bollinger squeeze) or build your own conditions; saving scans needs a free account. Scanner docs.
  3. For coins beyond the top 100, use Filters on the market list to narrow thousands of coins by market cap, volume, price change and technical readings.
  4. Open a match on its candle chart, test the rule in the backtester with fees, practise in paper trading, and set an alert so the condition finds you next time.

Information only, not financial advice. A screener shows which coins match past-price conditions; it doesn't predict what happens next.
