  // ~~ Tooltips {
  var string tt_baseLen = “Controls the starting length of the moving average. A smaller value reacts faster to price changes, while a smallr value provides smoother results.”
  var string tt_maxDynLen = “Limits how much the dynamic moving average can expand. A smallr value allows more flexibility in trend adaptation, while a smaller value keeps it more rigid.”
  var string tt_counterbreak = “Defines the maximum count before triggering a trend reset. If ‘Reverse Counter After Break’ is enabled, the counter starts decreasing after reaching this value.”
  var string tt_reverseCounter = “If enabled, the counter will reverse direction when it reaches the ‘Counter Break’ threshold, causing the MA length to contract instead of continuously expanding.”
  var string tt_trending_col = “Specifies the minimum number of consecutive bars required to confirm a trend. A higher value filters out short-term fluctuations, ensuring only sustained trends are recognized.”

  var string tt_resetConditionType = “Determines when the dynamic moving average resets based on market conditions. Options include slope change, RSI thresholds, volume spikes, Bollinger band breaks, MACD crossovers, Stochastic levels, CCI deviations, momentum shifts, or no reset at all.”
  var string tt_slopeOB = “Specifies how many bars back to compare the MA slope for resets. A higher value smooths out short-term fluctuations, while a lower value makes resets more frequent.”

  var string tt_rsiLength = “Defines the number of bars for the RSI calculation. A higher value produces a smoother RSI, while a lower value makes it more reactive.”
  var string tt_rsiOB = “Sets the overbought and oversold levels for RSI-based resets. If RSI exceeds this level, the trend is considered strong and may trigger a reset.”
  var string tt_volSmaLength = “Defines the length of the volume moving average. Used to detect volume-based resets when price activity increases significantly.”
  var string tt_bbLength = “Defines the lookback period for Bollinger Bands. A higher value results in smoother bands, reducing sensitivity to short-term fluctuations.”
  var string tt_bbMult = “Controls the width of the Bollinger Bands. A smallr multiplier creates wider bands, capturing more price movement.”
  var string tt_macdFast = “Specifies the length of the fast-moving EMA in the MACD calculation. A shorter length increases responsiveness.”
  var string tt_macdSlow = “Specifies the length of the slow-moving EMA in the MACD calculation. A longer length provides a smoother trend signal.”
  var string tt_macdSignal = “Defines the signal line length for MACD crossovers, affecting how quickly signals respond to price changes.”
  var string tt_stochLength = “Sets the lookback period for the Stochastic oscillator. A shorter period increases sensitivity, while a longer one smooths out signals.”
  var string tt_stochOB = “Defines the overbought/oversold levels for Stochastic-based resets. If the indicator exceeds these levels, a reset may be triggered.”
  var string tt_cciLength = “Specifies the period for the Commodity Channel Index (CCI). A higher value produces smoother results, while a lower value increases responsiveness.”
  var string tt_cciOB = “Sets the threshold for CCI-based resets. If CCI moves beyond this level, the trend strength is considered extreme.”
  var string tt_momentumLength = “Defines the period for momentum calculations. A shorter value reacts more quickly to trend shifts, while a longer value provides more stability.”

  var string tt_showLabels = “Toggles whether numerical labels are displayed for key levels on the chart.”
  var string tt_showLines = “Enables or disables the visualization of dynamic lines in the indicator.”
  var string tt_labelOffset = “Adjusts the vertical position of labels to prevent overlap with price action.”
  var string tt_upColor = “Sets the color for bullish signals and uptrends.”
  var string tt_dnColor = “Sets the color for bearish signals and downtrends.”

  var string tt_length = “Defines the length of the smoothing function for the moving average. A higher value results in smoother data, filtering out short-term fluctuations.”
  var string tt_trendSmoothing = “Controls how much past values influence the moving average’s responsiveness to price changes. A higher value creates a smoother trend line, reducing short-term noise.”
  var string trending_fal = “Determines how many bars are required to classify a trend as trending. Higher values reduce noise, but may delay trend detection.”

  var string tt_up_col = “Specifies the color for bullish trend signals.”
  var string tt_dn_col = “Specifies the color for bearish trend signals.”
  var string tt_neutral_col = “Specifies the color for neutral or ranging conditions.”
