Custom CVD Pine Script Indicator

I want a faithful Pine Script v6 recreation of TradingView’s Cumulative Volume Delta, then taken a step further with alert logic and simple style controls.

The number-one requirement is a rock-solid alert that fires the instant any candle from 09:30 to 16:00 EST touches or crosses the zero line. That alert must work on every chart interval from 1 minute through 1 hour.

Beyond that core alert, I also need: • A drop-down style setting that lets me switch the zero-line between line, dashed, and my preferred dotted rendering on the fly, plus an on/off toggle for showing the line at all. • Optional alerts for both gravestone and dragonfly doji closes inside the indicator pane (independent toggles so I can silence either pattern without editing code). • Full session and timeframe awareness so I’m never pinged outside the specified market hours or selected chart period.

Acceptance check: compile-error-free Pine v6 script, visually identical CVD plot, settings panel containing the controls above, and testable TradingView alerts that trigger exactly as described.

Hand over the.pine file and a short guide to creating the alert templates once the code is saved to a chart. Budget: USD 250–750 Skills: Financial Markets, Financial Analysis, Documentation, Data Visualization, Pine Script, Visual Design, Market Analysis, Backtesting
