The previous month's high and low are the big-picture lines the whole market trades around. They mark where last month's move ran out of steam — the kind of level that decides whether a trend continues or reverses for weeks.
Monthly H/L Lines draws them automatically — the prior-month high, low and midpoint, the monthly open, and as many months back as you want — clean, labeled, and out of your way.
A break of last month's high or low is a higher-timeframe expansion signal; a rejection there is a major fade. The midpoint is a fair-value pivot for the month, and the monthly open separates the bulls from the bears for the period.
When levels from different months stack on the same price, the confluence flag tells you — those are the heaviest levels on the chart.
Higher-timeframe levels are easy to forget when you're staring at a 5-minute chart. We wanted them always on, styled to match, and labeled clearly — the macro structure sitting quietly behind your intraday trading.
It won't predict the bounce — no indicator will. What it does is make sure you're never surprised by a monthly level again. Every line, label, color and extension yours to set, any instrument, no volume needed. Free, lean, no bloat, no upsell — built by a working futures trader.
Price runs into last month's high and stalls — a level the whole market can see. Rejections there are some of the cleanest fades on any timeframe.
A close beyond the prior-month high or low is expansion territory — the market accepting prices outside last month's range. Trade the retest, or trail the move with the level behind you.
Two or three months stacked on the same price — flagged automatically — is where the heaviest reactions happen. Mark it before the session, not after the bounce.
Above the monthly open, the month's buyers are in control; below it, the sellers. One line that keeps your intraday trades on the right side of the bigger picture.
None of these are trade signals — they're the levels the market already watches, drawn for you. The entries, the stops and the discipline are still yours.
