How to Use RSI Indicator on Firstock: Pro Guide for Smart Traders

Understanding technical indicators can be overwhelming, but the Firstock Option Trading App simplifies the process beautifully. In this revamped guide, we’ll cover exactly what is RSI indicator, how to use RSI indicator smartly, identify RSI indicator buy and sell signals, and leverage Firstock’s unique strengths for effective trading. Whether you're starting or already trading, this article focuses on clarity, value, and a professional approach—not gimmicks.

Introduction to RSI: Basic Concept

The Relative Strength Index (RSI) is a popular and powerful momentum oscillator that traders worldwide rely on. It helps you understand the strength and speed of price movements for any stock or asset.

Think of the case where you are running behind a runner, you may notice that the runner is over pushing herself or himself and may anticipate that the runner may slow down soon. RSI operates on the same principle - it is an indicator that price momentum may have reached an excessive point and a reversal might occur.

RSI assists traders to predict possible reversals or trend extensions prior to their occurrence providing an advantage in timing entries or exits.

How RSI Is Calculated & Default Settings

RSI calculations are technical but done automatically by charting tools, so you don’t need to compute anything yourself. Here’s how it works in short:

  • RSI = 100 – (100 / (1 + RS)) where RS (Relative Strength) is average gain / average loss over a defined period.
  • The default period used by most traders is 14 time periods (e.g. days on a daily chart).

That 14-period setting helps balance responsiveness and reliability in RSI signals. If you choose shorter periods, signals become quicker but potentially less stable; longer periods smooth out signals more.

What RSI Values Mean: Overbought, Oversold, Neutral

One of the key strengths of RSI is its easy-to-read scale from 0 to 100. 

  • Above 70: Generally considered overbought. This means price momentum may have peaked.
  • Below 30: Generally considered oversold — price may be undervalued in the short term.
  • Between 30 & 70: Neutral zone — price momentum is stable; no extreme reading.

Understanding where RSI stands helps you interpret market strength and potential reversals with clarity—critical for timing trades.

Identifying RSI Indicator Buy and Sell Signals

RSI gives actionable signals when interpreted properly. Below’s how to spot them:

Buy Signals

  • RSI dips below the oversold threshold (e.g. 30), then climbs back above it.
  • This signals rising momentum after potential weakness, offering a buy opportunity.

Sell Signals

  • RSI goes above the overbought level (e.g. 70), then falls back below it.
  • Indicates potential exhaustion in upward momentum—could be a selling or exit signal.

You can also use mid-point (50) to gauge momentum direction: often, readings above 50 may indicate bullish bias and below 50 may indicate bearish bias. Some traders use it for extra confirmation. 

Understanding RSI Divergence & Failure Swings

For advanced signal identification, two powerful concepts are divergence and failure swings:

Divergence

  • Bullish divergence: Price makes a lower low, but RSI makes a higher low → signalling weakening downward momentum and potential reversal.
  • Bearish divergence: Price makes a higher high, but RSI forms a lower high → warning of weakening upward momentum.

Failure Swings (Swing-Failure Pattern)

  • RSI moves into overbought or oversold territory, pulls back, attempts again, fails to surpass previous extreme, then moves opposite efficiently. This setup can be a strong reversal signal without relying on price alone.

These methods make your strategy robust by adding contextual confirmation—not just relying on raw levels.

Using RSI in Trend vs Range Markets

While the standard overbought/oversold rule works well, interpretation should adapt to market conditions:

  • In trending markets, stocks may stay overbought or oversold for extended times. Using RSI alone in such markets may generate false signals.
  • Traders often adjust thresholds during strong trends—some use tighter or relaxed zones to avoid early exits.
  • In range-bound markets, RSI works remarkably well: overbought → sell/exit, oversold → buy/enter.

Hence, always combine RSI reading with an understanding of the overall market condition before acting.

Here’s a practical walkthrough on using RSI via Firstock:

  2. Navigate to the chart view for any stock, index, or asset you're interested in.
  3. Locate the Indicators menu or section—Firstock offers advanced chart tools suitable for technical analysis.

Using Firstock’s smooth interface and responsive charts makes this process quick and efficient—ideal for traders who want speed without complexity.

Suggested RSI Trading Strategies for Beginners & Pros

Here are tested, simple strategies structured for clarity and success:

Strategy A: Basic Oversold/Overbought Swing

  • Wait for RSI to go below 30 → signal of oversold condition
  • Confirm price support or chart pattern
  • Enter long (buy), set stop-loss below recent swing low
  • Exit/Take profit when RSI goes above 70 or according to risk strategy

Strategy B: Divergence Reversal Entry

  • Spot bullish/bearish divergence between price and RSI (see section 5)
  • Use a lower time-frame confirmation in Firstock chart before executing
  • Manage risk strictly if price moves against signal

Strategy C: Trend-Based Pullback Setup

  • Identify the overall price trend (up or down)
  • In an uptrend: look for RSI pullbacks (e.g. from above 70 down toward 50 or 40) to enter long trades
  • In a downtrend: look for RSI rallies (e.g. from oversold zones) to enter shorts or exit longs

Keep in mind: no strategy is foolproof. Even the best RSI setups need risk management and confirmation.

Combining RSI with Other Tools for Confirmation

RSI performs best when combined with complementary indicators/analysis techniques:

  • Moving Averages (MA): Helps identify trend direction; if RSI says oversold but price is below a key MA, wait for alignment.
  • Support & Resistance Levels / Price Action: Chart patterns + RSI strengthen setup reliability.
  • Volume Analysis: Rising volume during breakout/crossover signals validates moves around RSI levels.
  • Other Indicators (e.g. MACD, Bollinger Bands): Use them as filters—not to confuse, but to confirm.
  • Trendlines on RSI Chart: Drawing trendlines directly on RSI can show momentum breakout/weakness independent of price.

This multi-layered confirmation reduces risk, increases clarity, and prevents false signals.

Risk Management & Avoiding Common Pitfalls

While RSI is a popular tool, it’s not infallible. Here are common mistakes and risk solutions:

Mistake

Solution

Blindly buying/selling just because RSI crosses 30 or 70

Always look for price/volume/context confirmation before trade.

Ignoring market trend before using RSI signals

Check trend direction before acting on RSI.

Over-trading based on every RSI signal

Be selective—quality trades over quantity.

Using inappropriate stop loss or risk sizing

Use calculated stop loss, risk-reward ratio, and don't over-leverage.

Relying on RSI solely for complicated assets & volatile periods

Supplement with other tools and adapt to volatility.

Good risk management will protect capital and improve longevity in trading, especially when experimenting with momentum indicators like RSI.

Optimizing RSI Settings Based on Time-Frame & Asset Type

Although the 14-period setting works generally, you can fine-tune it according to your trading style or the asset:

  • Short-term / intraday traders: Try shorter periods (e.g. 9 or 7) for quicker signals—but expect more noise.
  • Swing or long-term traders: Stick with default 14 or even longer to avoid over-reacting to minor moves.
  • Volatile assets (Futures & Options, high-beta stocks): Monitor RSI readings more conservatively; use combined strategies for safety.
  • Less volatile assets or indices: Standard settings often deliver reliable setups; just adjust risk tolerance accordingly.

Any change in settings must be back-tested (using past charts or paper trading) to ensure it works for that asset type and strategy.

Realistic Expectations: What RSI Can and Cannot Do

It’s important to keep your expectations realistic about what RSI can deliver:

What RSI can do:

  • Offer signals on momentum strength and possible reversals
  • Help you time entries/exits better when used properly
  • Assist in building structured strategies with logic

What RSI cannot guarantee:

  • Never works perfectly in all market conditions—false signals can and do occur, especially during strong trends or high volatility.
  • Should not be used in isolation without price context or risk controls
  • Cannot predict external factors (news events, macro shifts) that can override technical indicator signals

By combining RSI signals with good strategy, context, and discipline—especially via tools in Firstock—you can trade smarter and more sustainably.
