// Aggressive RSI Condition: RSI above a lower overbought threshold.
rsiSignalFlag = rsiValue > rsiAggThreshold

// Aggressive Bollinger Bands Condition: Price is above the upper band (suggesting an overextended rally).
bbSignalFlag = close > bbUpper

// Aggressive Stochastic Condition: Look for a crossunder of the aggressive threshold.
stochSignalFlag = ta.crossunder(k, stochAggThreshold)

// Aggressive ADX Condition: Market shows trend strength above the lower threshold.
