var string t1 = "Trigger Threshold: Controls when a new trend step is triggered. It's a multiplier of the ATR — higher values require a stronger price move to flip the trend direction."
var string t2 = "Max Step Size: Defines the maximum allowed size for each trend step, based on ATR. Use a negative number to scale down large step jumps in volatile conditions."
var string t3 = "Band Multiplier: Expands or contracts the volatility bands around the trend line. A higher value creates wider channels to account for more price fluctuation."
var string t4 = "Trend Hold: After a trend flip, the trend will hold for this many bars before another flip can occur. Useful for avoiding rapid flip-flopping in choppy markets."
var string t5 = "Retest Signals: Enables triangle markers on the chart when price re-tests the upper or lower channel boundary. Helpful for spotting potential continuation or bounce zones."
var string t6 = "Trend Filter: Only show retest signals if they align with the current trend direction (e.g., only show upper retests in a downtrend)."
var string t7 = "Trend Step Signals: Shows circular markers each time a new step is taken in the trend direction. These mark every structural trend advancement."
