2-candle pattern based on your 1-candle condition

Below is your original 1-candle logic, extended to detect a pattern where both the current candle and the previous candle satisfy the same condition.

Logic explanation:

• c1: the candle’s total range is smaller than or equal to 6.1 * pipsize.
• c2: the wick on the closing side is very small (≤ 0.8 * pipsize).
• If the candle is bullish (close > open): upper wick = high – close.
• If the candle is bearish (close < open): lower wick = close – low.
• Cond: candle satisfies both conditions c1 AND c2.
• 2-candle pattern: current candle Cond AND previous candle Cond[1] are both true.

ProBuilder code for the 2-candle pattern:

// --- 1-candle condition ---
Irange = high - low

c1 = Irange <= 6.1 * pipsize

IF close > open THEN
 c2 = (high - close) <= 0.8 * pipsize
ELSIF close < open THEN
 c2 = (close - low) <= 0.8 * pipsize
ELSE
 // Doji case: you can decide what to do; here we set it to FALSE
 c2 = 0
ENDIF

Cond = c1 AND c2

// --- 2-candle pattern: current candle AND previous candle match the same condition ---
TwoCandlePattern = Cond AND Cond[1]

RETURN TwoCandlePattern
