RSI کیا ہے؟ ریلیٹو اسٹرینتھ انڈیکس حقیقی اعداد کے ساتھ

RSI is not a forecast, not a buy or sell signal, and not a measure of value. It is a compressed summary of recent momentum, and almost every mistake made with it comes from asking it to be something more.

How Is RSI Calculated?

RSI takes a lookback period, 14 candles by default, splits those candles into ones that closed up and ones that closed down, averages each group, and divides one average by the other. That ratio is called relative strength (RS), and the formula RSI = 100 minus (100 divided by 1 plus RS) squeezes it onto a 0 to 100 scale.

Here is the calculation with real figures. Take 14 hourly gold candles. Eight closed up, and their gains add up to 24.00 dollars. Six closed down, and their losses add up to 9.00 dollars.

• Average gain: 24.00 divided by 14 = 1.714
• Average loss: 9.00 divided by 14 = 0.643
• RS: 1.714 divided by 0.643 = 2.667
• RSI: 100 minus (100 divided by 3.667) = 100 minus 27.3 = 72.7

Now reverse it. Six up candles totalling 9.00 dollars of gains, eight down candles totalling 24.00 dollars of losses. RS becomes 0.375, and RSI comes out at 27.3. The symmetry is the point: RSI near 70 means gains have recently outweighed losses by roughly two and a half to one, and RSI near 30 means the opposite. That is the entire content of the number.

One technical detail most explanations skip. After the first calculation, Wilder's original method does not recompute a simple average each candle. It smooths: the previous average gain is multiplied by 13, the new gain is added, and the total is divided by 14. This is why your platform's RSI will not match a spreadsheet using plain averages, and why RSI reacts more slowly than a raw calculation suggests.

What Do the RSI Levels Actually Mean?

Note how different the middle column is from the right one. "Overbought" sounds like a verdict about price being too high. The calculation contains no such claim. It is a description of what already happened, stated in the past tense, and nothing in it points forward.

Does RSI Above 70 Mean Sell?

No, and treating it that way is the most expensive misunderstanding in technical analysis. In a strong trend RSI can sit above 70 for weeks, and every one of those days is a day someone shorted into strength and paid for it.

The mechanism is simple once you look at the formula. RSI rises because gains have been large relative to losses. That is the definition of a strong uptrend. So RSI above 70 is not evidence a move is exhausted; it is evidence the move has been powerful. During gold's strongest legs, daily RSI has held above 70 for extended stretches while price continued higher.

The practical adjustment experienced traders make is to read RSI differently depending on what the market is doing. In a ranging market, 70 and 30 mark the edges of a range that has been holding, and mean reversion has some historical basis. In a trending market, the useful levels shift: in an uptrend RSI tends to bottom around 40 to 50 rather than 30, so a pullback into that zone is a continuation reading, not a reversal one. Knowing which of those two states you are in matters more than the RSI value itself, which is why reading structure on the chart comes before reading any oscillator.

What Is RSI Divergence, and Can You Trust It?

Divergence is when price makes a higher high but RSI makes a lower high, or price makes a lower low while RSI makes a higher low. The interpretation is that the move is continuing without the momentum that drove it earlier.

It is a real observation and worth noticing. It is also one of the least reliable signals in common use, and the honest reason is structural: divergence appears repeatedly during a healthy trend, because a trend decelerating for a few candles is ordinary, not terminal. A trader who shorts every bearish divergence in an uptrend will be right eventually and broke first.

Divergence is best used as a reason to tighten risk management on a position you already hold, or to demand more confirmation before entering, rather than as an entry trigger of its own. It tells you momentum is fading. It does not tell you when, or whether, price will follow.

Which RSI Setting Should You Use?

The default 14 is the sensible starting point, and changing it is a trade-off rather than an improvement. A shorter lookback such as 7 reacts faster and reaches 70 and 30 far more often, which means more signals and a much higher share of false ones. A longer lookback such as 21 is steadier and rarely reaches the extremes at all.

Be honest with yourself about why you would change it. Shortening the period until an indicator produces the signals you were hoping to see is not analysis, it is curve fitting on a chart, and it is the same failure that shows up in backtesting a strategy against live results. Pick a setting, keep it, and judge it over a large enough sample to mean something.

How Should RSI Fit Into a Trading Plan?

As one input among several, and never as the thing that decides your risk. An RSI reading has no bearing on how much you should lose if you are wrong, which is set by your stop distance and your position size, and that arithmetic is covered in risk and reward and in volatility.

The honest summary is that RSI is a genuinely useful descriptive tool and a genuinely poor predictive one. It compresses recent momentum into one number you can read at a glance, which is worth having. It does not know where price is going, and no indicator does.

That is also why TIC judges its own work on independently verified outcomes rather than on how good a setup looked on the chart. The full Myfxbook record, winning months and losing ones, is published at /results.
