If you have opened IDBI Bank’s share page on a stock app recently, you may have noticed a number labelled “RSI” sitting somewhere near the price. On 12 October 2026, several Indian finance websites, including Groww, Upstox, Kotak Neo and ScanX, were showing the RSI of IDBI Bank at around 45 — roughly between 45.09 and 45.33 — while the share traded near Rs 83.1. Most of these sites labelled that reading “Neutral”.
In one line: an RSI near 45 simply means the share was neither moving up too sharply nor falling too sharply in recent days. It was somewhere in the middle.
That number will not stay at 45. RSI moves every time the price changes, so the live value may be different by the time you read this. Use this article to understand the number, and always check the live figure on your app.
What Is RSI?
RSI stands for Relative Strength Index. It is a momentum indicator — in simple words, it measures the speed and strength of recent price movement. It does not look at the bank’s profits, loans, or any news. It only looks at price: how much the share has gained on its good days compared with how much it has lost on its bad days.
The indicator was developed by J. Welles Wilder, who introduced it in 1978 in his book New Concepts in Technical Trading Systems. Nearly five decades later, it is still one of the most widely displayed indicators, which is why almost every Indian broker app shows it by default.
RSI is a single line that moves between 0 and 100. When recent gains have been strong compared with recent losses, the line climbs. When losses have dominated, it sinks. Most platforms use a 14-period setting, written as RSI (14). On a daily chart, that means the last 14 trading days. This is the default Wilder suggested, and the setting behind the figure mentioned above.
How RSI Is Calculated
You do not need to calculate RSI by hand — your app does it instantly. But knowing the basic maths helps, because it explains why the number behaves the way it does.
The formula has two parts. First, you work out something called Relative Strength, or RS:
RS = Average gain over the period ÷ Average loss over the period
Then RS is converted into the 0-to-100 scale with this formula:
RSI = 100 − [100 ÷ (1 + RS)]
Here is the process, step by step:
- Look at the closing prices of the last 14 trading days.
- For each day, note whether the share closed higher or lower than the previous day, and by how much.
- Add up all the gains and divide by 14 to get the average gain. Do the same with the losses to get the average loss. Days with no change count as zero.
- Divide the average gain by the average loss. That gives you RS.
- Put RS into the second formula above. The result is your RSI, a number between 0 and 100.
A small worked example
The table below is a simplified example using five days instead of fourteen, just to show the logic. These are not IDBI Bank’s actual prices.
| Day | Closing price (Rs) | Daily change | Gain | Loss |
|---|---|---|---|---|
| 1 | 80.0 | — | — | — |
| 2 | 81.0 | +1.0 | 1.0 | 0 |
| 3 | 80.4 | −0.6 | 0 | 0.6 |
| 4 | 81.6 | +1.2 | 1.2 | 0 |
| 5 | 81.2 | −0.4 | 0 | 0.4 |
| 6 | 82.0 | +0.8 | 0.8 | 0 |
Total gains are 3.0 and total losses are 1.0. Average gain = 3.0 ÷ 5 = 0.6. Average loss = 1.0 ÷ 5 = 0.2. So RS = 0.6 ÷ 0.2 = 3, and RSI = 100 − [100 ÷ (1 + 3)] = 75. That makes sense — gains were three times the size of losses, so momentum was clearly on the upside. The real 14-day calculation is less tidy, but the idea is the same.
RSI of IDBI Bank: How to Read the Current Value
Readers generally divide the RSI scale into three zones. The table below shows the standard way these zones are described.
| RSI value | Zone | What it usually suggests |
|---|---|---|
| Above 70 | Overbought | The share has risen quickly in a short period and momentum has been very strong on the upside. |
| Between 30 and 70 | Neutral | Gains and losses have been fairly balanced. No extreme momentum in either direction. |
| Below 30 | Oversold | The share has fallen quickly and recent losses have been much heavier than recent gains. |
A reading in the mid-40s, like the current one mentioned at the start of this article, sits comfortably inside the neutral band, a little below the mid-point of 50. In plain words, over the previous two weeks of trading the share’s up moves and down moves had been fairly evenly matched, with a slight tilt towards the downside. There was no sign, from this indicator alone, of an extreme move in either direction.
Two words in that table need care: “overbought” and “oversold”. They sound like verdicts on the price. They are not. They only describe recent momentum — a share can stay overbought for weeks during a strong rise, or oversold for a long time during a steady fall.

Where to Check IDBI Bank RSI Live
Because RSI changes with every price move, the figure on this page is only a snapshot from one date. For the current value, check one of these types of sources:
- Your broker or demat app — most Indian broker apps show RSI on the share’s technicals or charts section. IDBI Bank trades on NSE under the symbol IDBI and on BSE under the code 500116.
- Finance portals — sites such as Groww, Upstox, Kotak Neo and ScanX publish a technical summary for the share, usually including RSI (14).
- Charting platforms — on TradingView and similar platforms, you can add RSI yourself below the price chart and change its settings.
Do not be surprised if two sites show slightly different numbers, such as 45.09 on one and 45.33 on another. Sites update at different times and may round differently. A fraction of a point makes no practical difference to how you read the zone.
RSI on Different Timeframes: Why Values Differ
This confuses many beginners. You check IDBI Bank and RSI shows 48. A friend checks at the same time and sees 62. Neither of you is wrong — you are probably looking at different timeframes.
RSI (14) means 14 periods, but a “period” depends on the chart. On a daily chart it is 14 days, on an hourly chart 14 hours, on a weekly chart 14 weeks. The same share can look calm on a daily chart and busy on an hourly one, if it rose sharply during the morning session.
The setting can also be changed: RSI (7) gives a faster, jumpier line, RSI (21) a slower one. The sites quoted here use the standard 14-period daily setting. When comparing figures from two places, first check that both use the same timeframe and setting.

Common Mistakes Beginners Make With RSI
Treating “overbought” as an automatic sell signal. The most common error. RSI crossing 70 only says the recent rise has been fast. Strong shares often keep rising while RSI stays above 70 for days. The zone is information, not an instruction.
Ignoring the overall trend. In a long uptrend, RSI may rarely drop below 40. In a long downtrend, it may rarely cross 60. Reading the number without the wider price trend strips away most of its context.
Using RSI on its own. RSI knows nothing about the bank’s results, interest rates, or market mood, all of which move bank shares. It is one small input among many, alongside price charts, volume, and the company’s actual financial performance.
Assuming every website shows the same value. Timeframe, period setting, and update timing all change the number. Beginners sometimes worry over a difference that is just a settings mismatch.
Checking once and treating it as final. A reading taken on Monday morning can look quite different by Friday. RSI is a moving snapshot, not a fixed property of the share.
Frequently Asked Questions
What is the current RSI of IDBI Bank?
The latest checked value is given at the top of this article and was described as neutral by major Indian finance sites. RSI changes daily, though, so check your broker app or a finance portal for today’s live value before relying on any figure.
What does an RSI of 45 mean?
It falls in the neutral zone between 30 and 70. It suggests recent gains and losses in the share have been fairly balanced, with neither buyers nor sellers showing extreme momentum over the past 14 trading days.
Is RSI above 70 always a bad sign?
No. Above 70 is called the overbought zone, meaning the price has risen quickly. It is a description of momentum, not proof that the price will fall. Shares in strong trends can remain above 70 for extended periods.
Why does the rsi of idbi bank differ between Groww, TradingView and my broker app?
Usually because of different timeframes, different period settings, or simple update delays. If all three use a daily chart with a 14-period setting, the values should be close, though small differences of a point or less are normal.
Can RSI tell me whether IDBI Bank is a good bank?
No. RSI only studies past price movements of the share. It says nothing about the bank’s deposits, loan quality, profits, or service. Those questions are answered by the bank’s financial reports, not by a chart indicator.
Conclusion
The current RSI reading of IDBI Bank points to a share that has been moving without any strong momentum in either direction over the previous two weeks. That is all the number says. Understood properly — as a 0-to-100 measure of recent gains versus recent losses, calculated over 14 periods and best read in zones — RSI is a handy little gauge on your stock app. It becomes misleading only when it is treated as more than that.
