Two Indicators, and What They Cannot Do
How do you use a moving average and RSI without the mistake that costs most beginners money?
Use a moving average only for slope and side, meaning whether price sits above or below it and whether it is rising or falling. Read RSI(14) only as how large recent gains were against recent losses, and remember that moving averages whipsaw inside a range while RSI can hold an overbought reading for weeks inside a strong trend.

You can already tell whether a chart is trending or ranging. You now mark only the price levels that have mattered before.
This chapter adds two tools for reading what happens in between. It also names the exact market condition where each one misleads you.
- 20 / 50days in the MA pair
- 14candles inside RSI
- 70RSI's overbought line
- -₹3,200net loss, one whipsaw run
What a Moving Average Actually Is
A 20-day moving average is the last 20 closing prices, added up and divided by 20. It is redrawn each day, as the window of closes slides forward.
It cannot hold information that the price did not already carry. The average is built only from closing prices you have already seen.
A moving average shows you slope and side, and it stops there. Price above a rising 50-day MA is uptrend context, and nothing more.
The number itself, say ₹60,40,000, is only a reference point on the chart. Reading it as a buy or sell trigger is the first mistake.
Lag: The Cost of Smoothing
A 20/50 crossover fires well after the trend it reports has already turned. By the time it fires, price has usually moved several percent.
That gap is the price you pay for smoothing the noise out. The crossover confirms a move that happened, and confirmation always arrives late.
Price can peak at ₹63,00,000 and fall toward ₹57,00,000 while the 50-day average still rises. The average may roll over only near ₹60,60,000, which is ₹2,40,000 below the peak.
RSI in One Number, and the Costliest Trap
RSI(14) looks at fourteen candles and weighs recent gains against recent losses. It presses all of that into one number between 0 and 100.
A reading above 70 means one thing, and one thing only. Recent up-moves have been large when set next to recent down-moves.
That is the whole meaning of the reading, and RSI never says price must fall.
Each Tool Fails Where the Other Works
Moving averages struggle inside a range, where price has no real trend. A flat market can throw four 20/50 crossovers inside three weeks.
RSI carries the opposite weakness once a strong trend is running. It can hold an overbought or oversold reading for weeks while price keeps moving.
This is why trend against range came first, in the last chapter. Each indicator fails in exactly the condition where the other one works.
Adding more indicators does not fix either problem, because they share one input. MA, RSI, MACD and stochastics are all built from the same closing prices.
Five indicators agreeing is really one opinion, counted five separate times. Even tools that combine price data in other ways, such as AI-based signal engines, inherit both limits.
The numbers 20, 50 and 14 are conventions rather than laws of the market. Traders picked them because they work often enough, and habit did the rest.
Tuning those numbers until last year's chart looks perfect is a trap. You already know how that story ends, so of course the rule fits.
The next chapter looks at what actually moves the price of an asset.
Key takeaways
- A moving average is arithmetic on past closes, redrawn as the window shifts.
- Its number is a reference point, not a buy or sell instruction.
- Lag is the price of smoothing, not a failure of the tool.
- RSI above 70 means recent gains were large, nothing more.
- Moving averages whipsaw in a range, and RSI misleads inside a trend.
- Stacking indicators built on the same closes adds no new information.
