Edgecraft - Volume Surge

Edgecraft — Volume Surge highlights moments when trading activity meaningfully increases, by flagging candles where volume exceeds a user-defined percentage of the recent average. A sudden rise in volume often signals that participation has changed — more traders are involved, liquidity is improving, and price action may be transitioning from “noise” to “decision.”

What it does

At its core, this script compares the current candle’s volume to the average volume over a lookback period and triggers when that candle reaches your chosen threshold (example: 150%, 185%, 250%, etc.). When a surge happens, the indicator plots a marker and can also trigger alerts.

⸻

What problem it solves

A breakout, breakdown, or reversal that occurs on weak participation can fail quickly. This tool helps you quickly answer:
• “Is this move attracting real attention?”
• “Is volume expanding in the direction of price?”

Rather than trying to “predict,” it gives you a participation filter to support better decision-making.

How it helps your decision process

• Helps you start thinking in a top-down way: Price + Participation
• Makes it easier to spot when the market is actually “awake”
• Reduces confusion from random intraday wiggles by focusing on meaningful activity
• Adds a clean confirmation layer to breakouts, breakdowns, ORB moves, trend continuation, and reversals
• Helps identify when liquidity/attention returns after consolidation
• Useful as a “trigger condition” for scanners and alerts without needing heavy overlays

Key features
• Custom Volume Surge Threshold (%)
Choose exactly what “surge” means to you: 150%, 185%, 250%, etc.
• Volume Average Length
Control how sensitive the baseline is by adjusting the averaging period.
• Direction Filter (Any / Bullish / Bearish)
Only show surges aligned with candle direction if you want cleaner signals.
• RTH Filter (Exchange Time)
Optionally restrict signals to Regular Trading Hours to avoid thin-liquidity noise.
• Minimal chart markers
Diamond markers appear only when the conditions are met. Clean by design.

⸻

Alert system

The script provides two alert conditions:
• Bullish Volume Surge
• Bearish Volume Surge

This makes it easy to create alerts that match your trading bias:
• set separate notification tones,
• route them to different webhooks,
• or use them for different trade plans.

⸻

How to use it
• Breakout confirmation: A breakout with a bullish surge signal suggests stronger participation.
• Breakdown confirmation: A bearish surge signal can help validate downside continuation.
• Reversal check: If price flips but volume doesn’t expand, you may treat the move as lower quality.
• Intraday focus: Enable RTH filtering to prioritize higher-quality market hours.
