Crash Spike Trendline

CRASH SPIKE TRENDLINE 

Most standard indicators suffer from look-ahead bias or recalculate their past signals to look perfect in hindsight. This indicator is built differently:

• Permanent Object Locking: When a valid setup occurs, the indicator assigns it a unique ID based on the exact timestamp of the breakout. Once drawn, the trendline and grey box are permanently locked. It never deletes, shifts, or hides a historical signal just because a trade failed.

• Zero Look-Ahead Bias: It calculates resistance pivots using only historical price data that was genuinely available before the breakout occurred. It never uses future bars to calculate a past trendline.

• No Survivorship Bias: A signal is generated the exact millisecond the geometric rules (trendline intersecting the grey box) are met. It does not wait to see what price does next before deciding whether to show the arrow. What you see in history is exactly what happened live.

• Immediate Alerting: The alert fires in real-time on the live, forming candle (the rates_total - 1 bar) the exact moment the trendline physically crosses into the grey breakout zone. It does not wait for the candle to close, giving you the fastest possible entry signal.

• Smart Arrow Tracking: While the signal triggers immediately at the start of the intersection, the arrow is uniquely programmed to track the high of that live candle as it forms. Instead of getting buried inside the candle if price moves up, the arrow continuously pushes itself a few points above the highest wick, ensuring it remains highly visible exactly where the signal started.

• Spam Protection: It includes a deduplication filter ( lastAlertTime ) so that even if price rapidly bounces in and out of the trigger zone on a single candle, you only receive one clean alert per bar via your pop-up, phone push notification, or email.
