How to Read Buy and Sell Signals: A Beginner's Guide

A friend once forwarded me a Telegram "tip" — "BUY TATA STEEL NOW, TARGET 10%". No stop loss, no reason, no timeframe. That isn't a signal. That's a lottery ticket. Real buy and sell signals come with a reason and a plan, and learning to read them is one of the most useful skills you can build as a trader.

What a trading signal really is

A signal is just a condition on the chart that has, historically, tilted the odds in one direction. A MACD crossover, a breakout above resistance, a stock reclaiming VWAP on high volume — each of these is a reason to look at a trade. Good stock trading signals combine a few such reasons and then tell you exactly where you are wrong.

The four parts of every signal

Whenever I look at a signal — mine or from a tool like the AI Intraday Scout — I check four things:

• Direction: BUY (expecting a rise) or SELL (expecting a fall).
• Entry: the price where the trade makes sense. If the stock has already run far past it, I skip.
• Target: where I plan to book profit.
• Stop loss: the price that proves the idea wrong. This is the most important number on the card.

If a signal doesn't have a stop loss, I don't trade it. Full stop.

Reading entry, target and stop loss together

Look at the gap between entry and stop versus entry and target. Say a BUY signal on ICICI Bank shows entry ₹1,250, stop ₹1,242 and target ₹1,265. Your risk is ₹8 and your reward is ₹15 — a reward-to-risk of almost 1:2. That's healthy. If a signal risks ₹10 to make ₹5, the maths works against you even if it's right more often than not.

What signal strength tells you

Many scanners give a strength score, say out of 100. Think of it as "how many independent reasons agree". A 90 usually means trend, momentum, volume and price action all line up. A 60 means only some of them do. Higher strength doesn't mean a guaranteed win — it means a cleaner setup. I size up slightly on strong signals and keep size small on weaker ones.

Confirmation: don't jump on the first candle

Beginners love to buy the very first green candle. I prefer confirmation:

• Volume: a breakout on weak volume fails far more often. I want volume clearly above its recent average.
• Market trend: a BUY on Infosys works better when NIFTY itself is above its EMA 20 and positive for the day. Fighting the index is tiring.
• Price action: a bullish engulfing or hammer candle at support is better than a random green candle in the middle of nowhere. I cover levels in Understanding Support and Resistance Levels.

SELL signals are not scarier, just different

A SELL signal means you short or exit a long. Read it the same way — entry, target, stop — except the stop sits above the entry. For example, if Axis Bank breaks below the morning low with RSI rolling over from 65 and price slips under VWAP, a SELL makes sense with a stop just above the breakdown level.

Common mistakes I made reading signals

• Taking every signal. Pick the two or three cleanest per day.
• Moving the stop loss "just a little" when price approaches it.
• Ignoring the time of day. A signal at 3:10 PM has very little time to work.
• Not understanding the indicators behind the signal. If you're unsure what MACD or RSI is saying, read Understanding MACD, RSI and EMA Indicators first.

A quick checklist before you click buy

Does the signal have a clear reason? Is reward at least 1.5x risk? Is volume supporting it? Is the broader market on your side? Is there enough time left in the session? If you can answer yes to all five, the signal is worth considering. If you're new to day trading itself, start with What is Intraday Trading and How Does It Work on NSE.
