+rsiValue = ta.rsi(close, rsiPeriod)
+
+// 3. MACD to catch momentum shifts.
+[macdLine, signalLine, _] = ta.macd(close, macdFast, macdSlow, macdSignal)
+
+// 4. Bollinger Bands to identify potential exhaustion in rallies.
+bbBasis = ta.sma(close, bbLength)

+// 5. Stochastic Oscillator (using %K) for additional overbought signals.
+k = ta.stoch(close, high, low, stochLength)

+
+
+// === MANUAL ADX CALCULATION ===
+// Step 1: Calculate the True Range (TR)
+prevClose = nz(close[1], close)
+tr = math.max(high - low, math.max(math.abs(high - prevClose), math.abs(low - prevClose)))
+
+// Step 2: Calculate directional movements (DM)
+upMove   = high - nz(high[1])
+downMove = nz(low[1]) - low
+plusDM  = (upMove > downMove and upMove > 0) ? upMove : 0
+minusDM = (downMove > upMove and downMove > 0) ? downMove : 0
+
+// Step 3: Smooth the values using Wilder's RMA (smoothed moving average)
+atr       = ta.rma(tr, adxPeriod)
+smPlusDM  = ta.rma(plusDM, adxPeriod)
+smMinusDM = ta.rma(minusDM, adxPeriod)
+
+// Step 4: Calculate the Directional Indicators (DI+ and DI-)
+plusDI  = 100 * (smPlusDM / atr)
+minusDI = 100 * (smMinusDM / atr)
+
+// Step 5: Compute the Directional Index (DX)
+dx = 100 * math.abs(plusDI - minusDI) / (plusDI + minusDI)
+
+// Step 6: Smooth DX to get ADX
+adxValue = ta.rma(dx, adxPeriod)
+
+
+// === ENTRY CONDITIONS FOR A SHORT POSITION ===
+
+// Condition 1: Bear Trend Confirmation - Price is below the SMA.
+bearTrend = close < smaValue
+
+// Condition 2: Bollinger Bands - Price crosses under the upper band.
+bbCondition = ta.crossunder(close, bbUpper)
+
+// Condition 3: MACD - MACD line crosses below the signal line.
+macdCondition = ta.crossunder(macdLine, signalLine)
+
+// Condition 4: RSI - Check if RSI is overbought.
+rsiCondition = rsiValue > rsiOverbought
+
+// Condition 5: Stochastic - %K crosses under the overbought threshold.
+stochCondition = ta.crossunder(k, stochOverbought)
+
+// Condition 6: ADX - The market must have a strong trend.
+adxCondition = adxValue > adxThreshold
+
+// Combine all conditions for a short entry signal.
+shortEntryCondition = bearTrend and bbCondition and macdCondition and rsiCondition and stochCondition and adxCondition
