What is Break of Structure (BOS)?

A Break of Structure (BOS) occurs when the price of an asset decisively breaks below a support level or above a resistance level that has been holding for some time.

For example, if a stock has been ranging between $50 support and $60 resistance for weeks, a Break of Structure happens if the price breaks below $50 support or above $60 resistance with strong momentum.

Key characteristics of a BOS:

A BOS indicates the market sentiment has shifted and a new trend may be starting. It represents an opportunity for traders to enter into a high probability trade.

Why is BOS Important in Trading?

Identifying Breaks of Structure is crucial for traders for several reasons:

1. Signals Potential Trend Change

A BOS often precedes the start of a new trend. By identifying BOS early, traders can capitalize on emerging trends.

2. Provides Entry/Exit Points

BOS provides clear areas for traders to enter or exit trades. Traders may go long when price breaks resistance or go short when support breaks.

3. Confirms Other Indicators

A BOS can act to confirm signals from other technical indicators. This gives traders greater confidence in taking a trade.

4. Sets Stop Losses

The broken support or resistance levels become key areas to place stop losses. This helps with effective risk management.

In summary, trading BOS allows traders to capitalize on high probability setups with predefined entry, exit and stop loss areas.

How to Trade Break of Structure (BOS)

Here are the key steps for effectively trading Breaks of Structure:

1. Identify Key Support/Resistance Levels

Use technical analysis to identify significant support and resistance levels that price has respected for some time. These become breakout trigger levels.

2. Wait for Decisive Break

Wait patiently for price to decisively break the support or resistance level with strong momentum and high volume. Avoid premature entries.

3. Enter New Trend Direction

Enter the trade in the direction of the new trend once BOS is confirmed. Go long on resistance breaks and short on support breaks.

4. Set Stop Loss at Breakout Level

Place stop loss at the breakout level to control risk on the trade. Revise stop as trend progresses.

5. Take Partial Profits at Next Level

Book partial profits at the next significant support/resistance level in direction of trend. Move stop to breakeven.

6. Trail Stop Higher to Lock Gains

Trailing stop higher allows profits to run as long as trend remains intact. Exit when trailing stop is hit.

By following these steps, traders can refine high probability BOS setups into a rules-based trading strategy.

3. Long Entry Order Triggered

A buy stop order at $61 gets triggered on resistance breakout for long entry in direction of emerging uptrend.

4. Stop Loss Set

Initial stop loss is placed just below recent swing low at $55 to allow for some retracement.

5. Take Profit at Next Level

Partial profits booked near $67 resistance area. Remaining position left open to capture further upside.
