ICT Change of Character (CHoCH) and Break of Structure (BOS) for Futures Trading

The most common structure mistake is calling every break of a swing point a reversal. Price breaks a prior high, the trader labels it a change of character, shorts the move, and the trend simply continues. The two labels mean different things, and the difference decides which side of the market you take.

The two definitions

In ICT terminology, a break of structure (BOS) is a break of a prior swing point in the direction of the existing trend. In an uptrend, price takes out a prior higher high. In a downtrend, it takes out a prior lower low. It says the trend is still doing what it was doing.

A change of character (CHoCH) is the first break against the trend. In an uptrend, price closes below the most recent higher low. In a downtrend, price closes above the most recent lower high. It is a warning that the sequence of higher highs and higher lows may be ending. It is not, by itself, a reversal.

Neither label is a trade signal. A BOS tells you which direction to look for entries. A CHoCH tells you to stop looking for entries in the old direction and wait.

Defining the swing points, because that is the weak spot

These concepts depend on which swings you count, and different traders count them differently. Decide the rules in advance and write them down:

• How many bars on each side make a swing high or low on your chart?
• Does a break require a candle close beyond the level, or does a wick count?
• Which timeframe gives structure, and which gives entries?

Changing these definitions after the fact to make a past chart look clean is the main way traders fool themselves with structure. A close-based rule is stricter and gives fewer signals than a wick-based one, and neither is correct in itself.

A worked ES example (hypothetical levels)

1. ES makes a higher low at 5,285, then a higher high at 5,300.
2. It pulls back to a higher low at 5,290 and rallies to a new high at 5,310. That break above 5,300 is a BOS. The uptrend is intact.
3. Another pullback holds at 5,295, a higher low. Still intact.
4. Price then closes below 5,295, the most recent higher low. That is a CHoCH. Stop looking for longs.
5. Price bounces to 5,303, a lower high, and then closes below 5,290. That break of a prior low, in the new direction, is a BOS to the downside. Now the structure has shifted, and you can look for short entries.

The CHoCH in step 4 told you to stand aside. The BOS in step 5 is what confirmed the new direction. Entering at the CHoCH itself means you bet before the evidence.

Turning structure into an entry, stop and size

After a BOS in your direction, a common approach is to wait for a pullback into an order block or a fair value gap and enter there. The stop goes beyond the swing that defines the structure. If that swing is 5 points away, the dollar risk per contract is easy to calculate:

If you risk a fixed dollar amount, say $100, the stop distance sets the size. A 5-point stop allows 4 MES contracts and no full ES contract. The wider the structural stop, the smaller the position must be. Stops can slip, so the actual loss can exceed the planned one.

Using more than one timeframe

A simple layering uses a higher timeframe such as the 1-hour for direction, the 15-minute for the structure sequence, and a 1-minute or 3-minute chart for the entry. The idea is that when all three agree you have a clearer plan. Whether that alignment improves your results is a question for your own records, not an assumption. Alignment also reduces how many setups you get.

How to test it before you rely on it

Mark structure on historical charts without looking at what happened next, and log every BOS and CHoCH you would have traded. Record entry, stop, target, result and commissions. Then ask whether the sample is large enough. Thirty trades is not a proven edge. Fifty simulated trades is not live proof, and a simulated fill does not validate queue position or slippage. Keep the log, repeat in different market conditions, and treat any result as provisional.

How this relates to KPL

Key Price Levels are a separate tool. They are fixed reference prices anchored to the regular session opening print, and the standard ES and NQ map has four levels derived from full-session and after-hours travel. The levels don't move intraday, and the opening anchor isn't known before the regular session opens at 9:30 am Eastern, so completed anchored levels don't exist before then. Structure reading is a different layer, and whether combining the two helps you is something to test. See how KPL levels are built for the exact definition.
