In short: NinjaTrader 8 and a chart. That is all Monthly H/L Lines needs.
Five days of chart history is enough. Older months come from NinjaTrader’s monthly bars, so they show on a short chart too; a line then starts at the first loaded bar instead of its month’s first bar.
High, mid and low of the month in progress, moved the moment price sets a new extreme.
On by default: a year of months on one chart, the older ones dimmed step by step.
Show the mid of the current month and of any month back, on its own if you like.
Set every line and label up exactly the way you like it to look.
You might ask: why is this free, what is the catch? There is none. We want to change the market for third-party NinjaTrader tools, and giving our work away is part of how we do it.
To say it plainly: this market is overpriced and full of low-quality tools with missing features and bugs. Vendors charge hundreds of dollars for simple indicators. No indicator, add-on or tool will make you profitable. A good one makes your trading environment better, and you know that already, or you would not be here looking.
Our goal is the highest-quality products we can build, tools that make a real difference on the chart. We get there by testing hard: weeks on live charts before release, feedback from the traders who use them, and a close read of what the forums complain about. We offer a full refund within 14 days, we adapt tools for customers who ask, and we give most of our work away.
Most of our tools are free for a reason. We want you to try them, see the quality and the features for yourself, and not spend a dollar with us until you think a tool deserves it. We are a business and we intend to make money, by solving real problems for traders.
So yes, Monthly H/L Lines is completely free, no strings attached. If you like it, there are more free tools and paid ones priced well under what is usual in this market. Leave a review if you want to, good or bad, we read every one. If you have any questions, please email us at [email protected].

Four ways to trade around the levels the whole market already has marked. None of them is a signal; the entries, the stops and the discipline are still yours.
Price runs into last month’s high and stalls, at a level every swing and position trader can see. A rejection there is a fade with the whole market watching the same price.
Price closes beyond last month’s high or low and holds: the market accepting prices outside last month’s range. Trade the retest, or trail the move with the level behind you.
When two months’ highs, or two months’ lows, sit within a couple of ticks, the label says so: Prev High (Aug 2026) ~2M. Mark those stacked levels before the session, not after the bounce.
Above this month’s open, the month’s buyers are ahead; below it, the sellers. One line that keeps your intraday trades on the right side of the month.

Download the zip, then in NinjaTrader 8 go to Tools → Import → NinjaScript Add-On and pick the file. Add it to any chart from the Indicators list, where it is called MonthlyHLLines, and the monthly levels are drawn — most traders are done in under a minute. The step-by-step guide covers every message NinjaTrader can show and the update rule.
From 1 to 24, four by default, counting the current month. The older months come from NinjaTrader’s monthly bars, so they appear even when your chart has only a few days loaded; on a short history a line starts at the first loaded bar instead of its month’s first bar.
For every month: the high, the low and, if you switch it on, the midpoint. For the current month it can also draw the opening price. The current month has its own styles, dashed by default with the open dotted, and every line has its own color, width and dash. Lines start at the month’s first bar and run to the right edge by default; they can also span the whole chart, stop at the current bar, or be left off for labels only.
When a month’s high lands within a set number of ticks of another month’s high, its label says so — for example Prev High (Aug 2026) ~2M, meaning last month’s high sits on the high from two months back. Lows are checked against lows the same way. The distance is two ticks by default, up to 20, or zero to switch it off.
One row per month: its tag (Curr, Prev, 2M…), the month and year, its high and low, and the range as a percentage of the low, with the current month marked by an asterisk. It is off by default and sits in any corner you pick.
No. The monthly levels never pull the price scale, so a low from a year ago does not compress today’s bars. Scroll the price axis if you want to see a level that is off screen.
No. When nothing on the chart has changed — the same high, low and open for the month, no new bar, no setting touched — it skips the redraw entirely, which is almost every tick. If your chart ever lags with it on, email us: that’s a bug, not normal.
Email support, answered by the traders who built it. Bugs get fixed — this tool gets the same updates and support as our paid indicators.
Free, no card, no license key. Download it, import it, and the monthly levels are on your chart in under a minute.
Not for you if you want the tool to tell you when to buy and sell. Monthly H/L Lines marks the levels the market watches; the trade is yours.
