Pullback day trading strategy: entering inside an established trend (US stocks)

A pullback day trading strategy for US stocks: rather than buying strength, it waits for a pause inside it. Fewer trades, and the ones you get have a nearer reference for the stop.

1. The rule

# BUY if Price > Sma(600) and ChangeAngle(120) > 8: if Price <= Sma(120) and Strength > 100: Buy()# SELL if ProfitPct >= 2.0 or ProfitPct <= -1.0 or HoldTime >= 1500: Sell()

2. Two averages doing different jobs

Changing either average changes a different thing, which makes this far easier to tune deliberately than a single-condition strategy. Widen the long one and you trade fewer, larger trends; widen the short one and you demand a deeper pullback before entering. The fourth line is what separates a pullback from a reversal. If Strength has fallen below 100 by the time price reaches the short average, this is not a pause in an uptrend — it is the start of something else.

3. The angle scales with the window

ChangeAngle(120) > 8 is a slope in degrees, and the window is short on purpose. Using the same threshold on a longer lookback makes the entry go quiet — not because the idea stopped working, but because the condition got much harder without you touching the number.

4. What the round trip asks of it

The 2.0% target against a 1.0% stop needs 33% on paper and 58% with the measured 0.75% round trip (what day trading a US stock really costs). Pullback entries earn their keep here in an indirect way. Because the entry is nearer the short average, the stop can sit closer to a real reference rather than at an arbitrary distance — and a tighter stop with the same target lowers the break-even. That, rather than a better hit rate, is usually where the advantage comes from.

5. What to change first

Try the stop before the entry. If the pullback reference is genuinely useful, a 0.8% stop should not cost you much in win rate, and it moves the break-even from 58% to around 55%. Then check that you are not simply trading later versions of the same trend all day. Record the time between consecutive entries on the same symbol; if it is under a few minutes, the pullback is noise rather than structure.
