BOS (break of structure) means price closes beyond the last swing high or low in the direction of the trend, so the trend is continuing. CHoCH (change of character) means price closes beyond the last swing against the trend, which is the first warning that control may be shifting. Inducement is a minor swing that tempts traders into early entries before price sweeps it and moves on.
Market structure in SMC is the sequence of swing highs and swing lows that shows whether buyers or sellers are in control. BOS and CHoCH are the two events that tell you whether that control is continuing or changing.
BOS vs CHoCH is the first thing I teach in Smart Money Concepts, because every other tool (order blocks, fair value gaps, supply and demand) depends on reading structure correctly. If you label a break wrongly, you end up buying into a reversal or selling into a trend. This article is the written companion to Lecture 1 of my free SMC course in Hindi, with extra worked numbers for Bank Nifty.
If you are brand new, our beginner SMC guide gives the overview, and the practical SMC guide for Nifty traders covers sweeps and order blocks. Here we go slower on the building blocks: structure, BOS, CHoCH and inducement.
This is Lecture 1 of my free SMC course in Hindi. It covers market structure, BOS, CHoCH, inducement and structure mapping for Bank Nifty, so you can watch first and then use this article as your written notes.

Market structure is the pattern of swing highs and swing lows on a chart. Higher highs and higher lows mean an uptrend, lower highs and lower lows mean a downtrend, and a break of the pattern is what BOS and CHoCH describe.
Concept: a swing high is a candle high with lower highs on both sides, and a swing low is the mirror image. Chart logic: in an uptrend, each pullback holds above the previous low (higher low) and each push exceeds the previous high (higher high). As long as that pattern holds, buyers control the sequence. Common mistake: marking swings on every tiny wiggle, which produces a dozen "structure breaks" a day. Fix: mark structure on a timeframe you can trade, such as 15 minutes for intraday, and confirm direction on the 1-hour or daily chart.
A BOS breaks a swing in the direction of the trend and signals continuation. A CHoCH breaks a swing against the trend and signals a possible reversal. In an uptrend, a close above the last high is a BOS, and a close below the last higher low is a CHoCH.
| Feature | BOS | CHoCH |
|---|---|---|
| Direction vs trend | With the trend | Against the trend |
| What it suggests | Trend is continuing | Control may be changing |
| Bullish example | Close above the previous swing high in an uptrend | Close above the previous lower high in a downtrend |
| Bearish example | Close below the previous swing low in a downtrend | Close below the previous higher low in an uptrend |
| How to use it | Look for a pullback entry in the trend direction | Stop trading the old trend and wait for a new setup |
| Main risk | Chasing the break instead of waiting for a retest | Treating a single CHoCH as a confirmed reversal |
One CHoCH is a warning, not a verdict. A CHoCH that follows a liquidity sweep, and then gets a BOS in the new direction, is stronger evidence than a lone close beyond a swing. Many traders also require a candle close beyond the level instead of a wick, which filters some false breaks.
Inducement is a minor swing high or low that looks like an obvious entry or stop level. Price often sweeps it first, taking the orders resting there, and only then makes the real move. It is the reason early entries get stopped out just before the trade works.
Concept: traders see a small pullback low and buy on a break above, or place stops just under it. Those orders create liquidity. Chart logic: if price dips under that minor low, closes back above, and then holds a zone, the sweep removed weak hands and gave larger orders something to fill against. Common mistake: buying the first small low without waiting for it to be taken. Fix: ask where a retail trader would place a stop, and wait to see whether price takes it and rejects.
Inducement is an idea about how orders cluster, not a guarantee of what institutions do. Treat it as a filter that improves timing, and keep your stop beyond the swept low.
Start on a higher timeframe to set direction, mark the last swing high and low, wait for a BOS or CHoCH close, then look for inducement and a retest of the zone that caused the move. Entry, stop and target come from those levels, not from a guess.
In this illustrative bullish example, Bank Nifty breaks a swing high with a BOS, pulls back, sweeps a minor inducement low, and holds a demand zone. Entry is on the confirmation candle, the stop sits beyond the sweep, and the target gives 1:2. All levels are invented for teaching.
| Item | Level (illustrative) | Why it matters |
|---|---|---|
| Bias | Daily and 1-hour bullish | Trade direction agrees with the larger structure |
| Swing high / BOS | Close above 55,160 | Continuation of the uptrend |
| Higher low | 55,060 | Structure stays bullish while this holds |
| Inducement low | 55,100, swept to 55,075 | Early buyers and stops taken, price closes back above |
| Demand zone | 55,075 to 55,110 | Origin area of the BOS move |
| Entry | 55,125 after a bullish confirmation candle | Defined location, not a chase |
| Stop loss | 55,065 | Below the sweep low; if it breaks, the idea is invalid |
| Target | 55,245 | 2R, near the next liquidity above |
| Risk : Reward | 60 points : 120 points = 1:2 | Meets a minimum 1:2 filter |
Invalidation: a close below 55,065, or a CHoCH (a close below the 55,060 higher low). When not to take it: if the daily trend is bearish, if it forms in the opening minutes or near a scheduled event, or if resistance sits within about 60 points of your entry.
Lots equal your rupee risk divided by stop distance times lot size. Wider stops mean fewer lots, and sometimes none. The structure can be right and the trade can still hurt if the size is wrong.
NSE revised the Nifty Bank lot size from 35 to 30 for the January 2026 series, so this example uses 30. Lot sizes change periodically, so verify the current number on NSE or your broker platform. Formula: lots = floor(risk in rupees ÷ (stop points × lot size)). Example with ₹5,00,000 capital and 1% risk (₹5,000):
| Stop distance | Loss per lot | Lots allowed | Actual risk |
|---|---|---|---|
| 30 points | 30 × 30 = ₹900 | 5 | ₹4,500 |
| 60 points | 60 × 30 = ₹1,800 | 2 | ₹3,600 |
| 100 points | 100 × 30 = ₹3,000 | 1 | ₹3,000 |
| 250 points | 250 × 30 = ₹7,500 | 0 (skip) | Over budget |
In the worked example, a 60-point stop allows 2 lots: risk 60 × 30 × 2 = ₹3,600, and the 120-point target is worth 120 × 30 × 2 = ₹7,200 before costs. If you trade options instead of futures, convert the index stop into a premium stop first, because option prices move by delta and decay with time.
Most BOS and CHoCH errors come from marking the wrong swing, accepting wick breaks, or treating one break as proof. The fixes are simple rules written down before the session.
For the level framework that helps filter weak setups, see our intraday support and resistance guide.
Before any entry, confirm direction, the break, the zone, the sweep and the risk. If any item fails, waiting is the default.
When not to trade:
BOS is a break of a swing in the direction of the trend and signals continuation. CHoCH is a break against the trend and is the first warning of a possible reversal.
It is an early warning, not a confirmed reversal. A CHoCH followed by a liquidity sweep, a BOS in the new direction and a retest is stronger than a lone close beyond a swing.
Inducement is a minor swing that attracts early entries and stops. Price often sweeps it before the real move, so it helps with entry timing and stop placement.
Many traders use candle closes because wicks can be liquidity sweeps. Pick one rule and apply it consistently, then test it on past charts.
Yes, they are ways of reading swing structure and apply to any liquid chart. SMC is a popular framework, not a proven edge, so practise on paper first and risk a fixed small amount per trade.
There is no single best timeframe. A common approach is to set bias on the daily and 1-hour charts and mark entries on 5 or 15 minutes. Keep the same combination long enough to judge it.
Label structure first, then act. BOS keeps you with the trend, CHoCH tells you to pause, and inducement tells you not to rush the entry. Add a stop beyond the sweep and a lot size from your rupee risk.
