What Does Multi-Period High Measure?
Rather than a single 52-week high flag, Multi-Period High checks proximity to highs over multiple windows—intraday, short swing, and longer lookbacks depending on configuration—in one Trade Ideas field. A symbol printing new highs on several periods simultaneously shows aligned momentum across timeframes. Partial alignment—new 5-day high but not 20-day—describes early versus mature breakout stage. Scanners use boolean or ranked conditions to require “at multi-period high” before surfacing ticker.
Alignment across periods strengthens continuation thesis; misalignment warns you are early or late to move.
How Do Traders Use It in Trade Ideas Scans?
Classic momentum scan: price at Multi-Period High, relative volume elevated, TI Strength above threshold, above VWAP. Opening drive strategies filter names already at short-period high with long-period high not far—coiled continuation. Avoid chasing when only longest period high breaks while short periods show lower highs—potential exhaustion wedge. Save scan with explicit period parameters documented in strategy notes.
Pair with dollar volume minimum so high prints reflect tradable capital, not thin spike highs.
How Does Multi-Period High Relate to Donchian Breakouts?
Donchian upper band IS N-period highest high on chart. Multi-Period High aggregates several N values for scan logic without plotting each channel. You can require Donchian visual on chart while scan uses Multi-Period High for speed across universe. Both define breakout; redundant to also demand new high on five unrelated indicators—pick coherent stack.
When chart shows lower high but scan says short-period high, trust visual structure—lookback mismatch may explain divergence.
When Is Multi-Period High Misleading?
Low-float spike to new high on single print without RVOL—fades common. Gap up opens already at highs—all periods true at bell without organic trend. Reverse split distorts historical highs until data adjusts. High at long period but extended 5 ATR from VWAP—poor entry location despite scan hit. Always read distance from mean and support, not boolean high flag alone.
After halt resume, multi-period flags may reset—wait for stable prints before triggering orders.
How Do You Combine Multi-Period High With Multi-Period Low?
Long-only book: Multi-Period High for entries, avoid names at Multi-Period Low unless reversal setup defined. Pairs trading context: long sector leader at high, short laggard at low—spread idea. Range day: alternating flags on both sides—stand down until one side wins with volume. Trade Ideas lets both fields coexist in complex scans with AND/OR logic—test boolean grammar before live alerts.
Journal whether entry was first-period high or full alignment—expectancy often differs between stages.
