Donchian Channels plot the highest high and lowest low over a specified lookback period, creating a dynamic channel that defines the current price range. Originally popularised by the legendary Turtle Traders, Donchian Channel breakouts capture new trends at their inception by entering when price exceeds the prior range extreme. The channel width also serves as a volatility measure and position-sizing input.
The upper band is the highest high over the lookback period, typically twenty periods. The lower band is the lowest low over the same period. The midline is the average of the upper and lower bands. A breakout above the upper band signals a potential new uptrend. A breakout below the lower band signals a potential new downtrend. Channel width reflects current volatility — wider channels indicate higher volatility. The Turtle Trading system used twenty-period and fifty-five-period Donchian breakouts.
Enter long when price closes above the twenty-period upper Donchian Channel. Enter short when price closes below the twenty-period lower Donchian Channel. Use a longer period such as fifty-five periods for stronger, less frequent signals. Filter entries using the trend direction from a higher-timeframe Donchian Channel.
Exit long positions when price touches the ten-period lower channel (tighter trailing exit). Exit short positions when price touches the ten-period upper channel. Use the midline as a trailing stop for trend-following positions. Exit if the breakout fails to show follow-through within a few periods.

Donchian Channel breakouts produce many false signals in ranging markets, so trend filters are essential. The Turtle Traders combined Donchian breakouts with ATR-based position sizing and strict risk management to create one of the most successful systematic strategies in history. Simplicity is the strength of this approach — avoid over-complicating it with too many additional indicators.
Pivot points are mathematically derived horizontal levels calculated from the previous period's high, low, and close that serve as potential support and resistance for the current period. The central pivot point acts as the primary directional bias level, while support and resistance levels above and below provide profit targets and stop placement zones. Pivot points are widely used by institutional and floor traders, creating self-fulfilling price reactions.
Gaps occur when price opens significantly above or below the prior close, leaving an unfilled space on the chart. Gap trading strategies exploit the tendency for gaps to either fill (price returning to close the gap) or continue (price extending in the gap direction). Understanding gap types — common, breakaway, runaway, and exhaustion — helps traders determine whether to fade the gap or trade its continuation.
Bollinger Bands consist of a middle band (20 SMA by default) and upper/lower bands set at 2 standard deviations from the middle. The bands expand during high volatility and contract during low volatility. The squeeze (narrow bands) often precedes a significant move, making Bollinger Bands excellent for volatility-based setups.
The Moving Average Convergence Divergence (MACD) measures the relationship between two exponential moving averages (typically 12 and 26 period). The MACD line is the difference between these EMAs, and the signal line is a 9-period EMA of the MACD. The histogram shows the distance between MACD and signal lines. MACD is a hybrid trend-following and momentum indicator.
