// ===== Custom Functions for DEMA and TEMA =====
dema(src, length) =>
    ema1 = ta.ema(src, length)

    2 * ema1 - ema2

// ===== Configuration Parameters =====

// MA Type Selection
maType = input.string(title="MA Type", defval="EMA", options=["SMA", "EMA", "WMA", "DEMA", "TEMA"])

// Parameters for composite periods
periodA = input.int(title="Period A", defval=20, minval=1)
periodB = input.int(title="Period B", defval=30, minval=1)
compMethod = input.string(title="Composite Method", defval="Average", options=["Average", "Weighted"])

// Reaction percentage (e.g., 0.5 means 0.5%)
reactionPerc = input.float(title="Reaction %", defval=0.5, step=0.1)

// ===== Composite Period Calculation =====
compPeriod = compMethod == "Average" ? math.round((periodA + periodB) / 2) : math.round((periodA * 0.6 + periodB * 0.4))

// ===== Moving Average Calculation based on selected type =====
ma = switch maType
    "SMA"  => ta.sma(close, compPeriod)
    "EMA"  => ta.ema(close, compPeriod)
    "WMA"  => ta.wma(close, compPeriod)
    "DEMA" => dema(close, compPeriod)
    "TEMA" => tema(close, compPeriod)
    => ta.ema(close, compPeriod)  // Default value

plot(ma, color=color.blue, title="MA")

// ===== Trend Definition =====
trendUp = close > ma
trendDown = close < ma

// ===== Reaction Threshold Calculation =====
// In uptrend: expect the price to retrace to or below a value close to the MA
upThreshold = ma * (1 - reactionPerc / 100)
// In downtrend: expect the price to retrace to or above a value close to the MA
downThreshold = ma * (1 + reactionPerc / 100)

// ===== Quick Reaction Detection =====
// For uptrend: reaction is detected if the low is less than or equal to the threshold and the close recovers and stays above the MA
upReaction = trendUp and (low <= upThreshold) and (close > ma)
// For downtrend: reaction is detected if the high is greater than or equal to the threshold and the close stays below the MA
downReaction = trendDown and (high >= downThreshold) and (close < ma)

// ===== Trade Execution =====
if upReaction
    // Close short position if exists and open long position
    strategy.close("Short", comment="Close Short due to Bullish Reaction")
    strategy.entry("Long", strategy.long, comment="Long Entry due to Bullish Reaction in Uptrend")

if downReaction
    // Close long position if exists and open short position
    strategy.close("Long", comment="Close Long due to Bearish Reaction")
    strategy.entry("Short", strategy.short, comment="Short Entry due to Bearish Reaction in Downtrend")
