BTST Stock Scanner: Filters You Should Use for High-Probability Trades

Introduction

BTST (Buy Today, Sell Tomorrow) trading is one of the most popular short-term trading strategies among Indian stock market traders. The idea is simple—buy a stock before the market closes and sell it the next trading day to capture overnight price movement. However, the biggest challenge is identifying the right stocks that have the highest probability of making a profitable move.

This is where a BTST stock scanner becomes an essential tool. A stock scanner helps traders filter thousands of stocks based on technical and volume-based criteria, allowing them to focus only on high-potential trading opportunities.

In this guide, you’ll learn the best BTST stock scanner filters, why they matter, and how to combine them to improve your trading decisions.

What is a BTST Stock Scanner?

A BTST stock scanner is a screening tool that identifies stocks meeting specific technical, price, and volume conditions before the market closes.

Instead of manually checking hundreds of charts, traders use scanners to instantly find stocks showing signs of strong momentum, accumulation, or breakout setups.

Using the right filters can significantly increase the chances of selecting quality BTST trades while reducing unnecessary risks.

Why Stock Scanner Filters Matter

Many beginners make the mistake of buying stocks simply because they’re trending on social media or news channels.

Professional traders rely on data.

A properly configured BTST scanner helps you:

• Find stocks with strong buying momentum.
• Avoid weak or sideways stocks.
• Save research time.
• Improve trade accuracy.
• Reduce emotional trading decisions.

The better your filters, the better your stock selection.

Best BTST Stock Scanner Filters

1. High Volume Filter

One of the most important BTST filters is unusually high trading volume.

Look for stocks where today’s volume is at least 1.5x to 2x higher than the average 20-day volume.

High volume indicates institutional participation and strong buying interest.

Recommended Filter:

• Volume > 150% of 20-Day Average

2. Price Above 20 EMA

The 20-Day Exponential Moving Average (EMA) helps identify short-term trends.

For BTST trades, choose stocks trading above the 20 EMA because they usually have bullish momentum.

Recommended Filter:

• Current Price > 20 EMA

3. Breakout Above Resistance

Breakout stocks are excellent BTST candidates.

When a stock closes above an important resistance level with high volume, it often continues its momentum the next day.

Look for:

• 20-Day High Breakout
• 52-Week High Breakout
• Swing High Breakout

4. Relative Strength (RS)

A strong stock usually outperforms both the market and its sector.

If Nifty gains 0.5% but a stock gains 3%, it shows relative strength.

Choose stocks that remain strong even during market corrections.

5. Bullish Candlestick Pattern

Price action plays a major role in BTST trading.

Some reliable bullish candlestick patterns include:

• Bullish Engulfing
• Marubozu
• Hammer
• Three White Soldiers
• Strong Closing Candle

Avoid indecision candles like Doji unless supported by other confirmations.

6. RSI Between 55 and 70

The Relative Strength Index (RSI) helps identify momentum.

For BTST trading, an RSI between 55 and 70 often indicates healthy bullish momentum without being extremely overbought.

Recommended Filter:

• RSI >55
• RSI <70

7. Delivery Percentage

High delivery percentage indicates genuine buying instead of intraday speculation.

Stocks with increasing delivery volume often perform better in BTST setups.

Look for:

• Delivery Percentage Above 40%
• Increasing Delivery Volume

8. Gap Recovery Stocks

Sometimes stocks open lower but recover throughout the day and close near the day’s high.

This indicates strong buying pressure.

These recovery stocks often continue higher the next trading session.

9. Sector Strength

Even strong stocks struggle if their sector is weak.

Before selecting a BTST trade, check whether the stock belongs to a strong-performing sector.

Examples include:

• Banking
• IT
• Auto
• Pharma
• Capital Goods

Trading with sector momentum increases the probability of success.

10. Stocks Near Day’s High

A stock closing very close to its day’s high indicates buyers remained in control until the closing bell.

Avoid stocks that lose momentum before market close.

Ideal filter:

• Closing Price within 1% of Day’s High

Sample BTST Stock Scanner Setup

A powerful BTST scanner can include the following conditions:

• Price Above 20 EMA
• Volume > 2x Average Volume
• RSI Between 55–70
• Close Near Day High
• Breakout Above 20-Day High
• Delivery Percentage Above 40%
• Strong Sector Performance
• Bullish Candlestick Pattern

When multiple filters align, the probability of finding quality BTST opportunities improves significantly.

Risk Management While Using a BTST Scanner

Even the best scanner cannot guarantee profits.

Always follow proper risk management.

Use Stop Loss

Place a stop loss below the breakout level or previous day’s low.

Avoid Penny Stocks

Low-priced stocks are highly volatile and easier to manipulate.

Focus on fundamentally strong companies with good liquidity.

Avoid Trading Before Major Events

Corporate announcements, RBI policy meetings, election results, and quarterly earnings can create unpredictable overnight gaps.

Don’t Overtrade

Quality is more important than quantity.

One high-quality BTST trade is better than five random trades.

Common Mistakes Traders Make

Many traders misuse stock scanners by:

• Using too many filters.
• Ignoring overall market trend.
• Buying after extended rallies.
• Ignoring volume confirmation.
• Taking trades based only on RSI.
• Not checking news or earnings announcements.
• Forgetting risk management.

A scanner should support your analysis, not replace it.

Which Platforms Offer BTST Stock Scanners?

Several platforms provide customizable stock screening tools for BTST traders.

Popular options include:

• TradingView
• Chartink
• StockEdge
• Screener.in (for fundamental screening)
• Broker-specific scanners

Choose a platform that allows multiple technical conditions and real-time market scanning.

Final Thoughts

A BTST stock scanner is one of the most effective tools for identifying high-probability overnight trading opportunities. By combining filters such as high volume, price above the 20 EMA, breakout levels, RSI, sector strength, and delivery percentage, traders can significantly improve their stock selection process.

Remember that no scanner is perfect. Always combine scanner results with chart analysis, market sentiment, and disciplined risk management before entering any trade.

Successful BTST trading is not about finding the most stocks—it’s about finding the right stocks with strong technical confirmation and favorable market conditions.
