5 Trading Filter Ideas You Can Build in 30 Seconds

Filters you can use right now

One of the most common questions we get: “What should I scan for?”

Here are five filter ideas covering different trading styles. Each one is a natural language description you can paste directly into vyx. No coding. No configuration. Just paste, review the generated code, and activate.

1. The oversold bounce

Paste this:

Find coins where RSI crosses below 30 with rising volume on the 1h chart

What it catches: Pairs hitting oversold territory with increasing interest (volume). The volume component helps filter out low-conviction oversold readings where nobody is actually trading.

Timeframe: 1H is the sweet spot. Lower timeframes generate too much noise. Higher timeframes (4H, daily) are valid but fire less often.

What to watch for: RSI can stay oversold for extended periods in strong downtrends. This filter catches the initial move into oversold — pair it with your own support/resistance analysis before entering.

2. The trend continuation EMA cross

Paste this:

Find pairs where the 9 EMA crosses above the 21 EMA with RSI above 50 and above-average volume

What it catches: A classic trend continuation setup. The EMA crossover confirms short-term momentum, RSI above 50 confirms we’re in bullish territory, and above-average volume confirms real participation.

Why it works: This isn’t trying to catch reversals. It’s filtering for pairs where a trend is already established and momentum is accelerating. Lower risk entry than trying to call bottoms.

Timeframe: Works on 4H and daily. The 1H can work but generates more false signals.

3. The Bollinger Band reversal

Paste this:

Find pairs where price closed below the lower Bollinger Band on the previous candle and then closed back inside the bands on the current candle, with RSI below 35

What it catches: A move outside the Bollinger Bands followed by a snap back inside. This often indicates a short-term reversal. The RSI condition confirms the pair was legitimately oversold, not just expanding in a trend.

What makes this filter special: It looks at two consecutive candles — the previous one must be below the band, and the current one must be back inside. This temporal comparison is something traditional screeners can’t do.

Timeframe: Best on 1H or 4H.

4. The volume spike detector

Paste this:

Find pairs where volume is at least 3x the 20-period average and the candle body is larger than the ATR on the 15m chart

What it catches: Unusual activity. When volume explodes to 3x normal and the candle body exceeds the ATR (average true range), something is happening. Could be a breakout, news, or a large player entering.

How to use it: This is a momentum filter, not a directional one. The signal tells you something is happening — it’s up to you to assess direction and whether to participate.

Timeframe: 15m is good for quick detection. 1H if you want to filter out more noise.

5. The MACD histogram flip

Paste this:

Pairs where the MACD histogram has been negative for at least 5 bars and just turned positive, with price above the 200 EMA on the daily

What it catches: Pairs transitioning from bearish to bullish momentum while still in a long-term uptrend (above 200 EMA). The “at least 5 bars” condition ensures the bearish period was sustained, not just a single-bar blip.

Why the 200 EMA matters: You’re filtering for pullbacks within uptrends, not trying to catch falling knives. When the MACD flips positive above the 200 EMA, it’s often a continuation signal rather than a dead cat bounce.

Timeframe: Daily chart for this one. The 200 EMA on lower timeframes is less meaningful.

Tips for writing filters

A few things to keep in mind when describing your own filters:

• Be specific about timeframes. “On the 4H chart” is better than leaving it ambiguous.
• Combine conditions. Single-condition filters fire constantly. Two or three conditions together produce more meaningful signals.
• Volume matters. Adding a volume condition to almost any filter improves signal quality. “With above-average volume” is the easiest upgrade.
• Start wider, then narrow. If your filter fires too often, add conditions. If it never fires, remove some. The AI regenerates quickly.

Getting started

All five of these filters require a Pro ($29/mo) or Trader ($59/mo) plan. The free tier includes built-in filters that run across all pairs, so you can see the signal format before upgrading.

1. Go to Signals > Filters > New Filter
2. Paste one of the descriptions above
3. Review the AI-generated code
4. Activate and start scanning

Each filter scans every Binance futures pair on every candle close. Set it and forget it.
