Indicators

Indicators compress price history into one readable line. This chapter covers the six that earn their screen space — what each actually measures, the settings that suit NSE volatility, and how to combine at most two without paralysis.

Key takeaways

  • One trend indicator + one momentum indicator is plenty; more = slower decisions.
  • Indicators confirm structure — they never override broken support or trend.
  • Tune lengths to NSE volatility; defaults built for US large-caps often lag here.

Lesson 1

RSI: momentum gauge, not buy/sell button

  • Standard 14-period; overbought 70 / oversold 30 are context, not triggers.
  • In strong Nifty uptrends RSI pins above 50 — buy 50–60 pullbacks, not 30 tags.
  • Bullish divergence (price lower low, RSI higher low) at support warns of johnny-come-lately shorts.

Lesson 2

MACD: trend + momentum in one

  • 12/26/9 standard; histogram expansion shows acceleration, contraction warns early.
  • Trade crossovers only in the direction of the daily structure — counter-trend MACD crosses chop.
  • MACD above zero line = trade longs; below = shorts or stand aside.

Lesson 3

Supertrend and ATR trailing

  • Supertrend (10, 3) is India's favourite trend filter — green = hold longs, red = step aside.
  • Whipsaws in sideways Nifty phases; pair with a horizontal level before acting.
  • ATR-based stops (1.5–2x ATR) adapt to volatility better than fixed percentages.

Lesson 4

Bollinger Bands and VWAP

  • Bollinger squeeze (low bandwidth) precedes expansion — direction unknown until the break.
  • Walking the upper band = strength, not automatic short; wait for a close back inside.
  • VWAP is the intraday fair-price line: above = buyers in control, below = sellers. Institutions benchmark to it.

Lesson 5

Volume indicators: OBV and delivery

  • OBV rising with price confirms accumulation; OBV diverging warns of weak hands.
  • NSE delivery % + OBV together beat either alone for swing confirmation.
  • No indicator replaces price structure — if RSI says buy but structure breaks down, trust structure.

Mistakes that cost money

  • Shorting strong uptrends because RSI crossed 70.
  • Flipping Supertrend on every 15-minute flip in a sideways market.
  • Stacking RSI + Stochastic + MACD and waiting for unanimous agreement that never comes.

Chapter FAQ

Which two indicators for beginners?

50-DMA (trend) + RSI-14 (momentum timing at pullbacks). Add VWAP intraday and Supertrend for trailing once those two feel natural.

Best Supertrend settings for NSE?

10, 3 is the common starting point for daily charts. Shorten to 7, 3 for intraday 15-minute charts and accept more whipsaw on range days.

Why does RSI stay overbought in rallies?

RSI measures velocity, not value. Strong trends sustain high velocity for weeks — overbought readings describe strength, and shorts against them fund the rally.
