Live group Q&A / implementation session for this intake
This started with a simple observation about the Williams %R indicator - one of Larry Williams' original tools and one that most traders either ignore or misuse.
I've interviewed Larry directly. I understood the indicator. Then I came across a modification that Dr. Ken Long of Tortoise Capital had developed that extended its functionality in an interesting way. I took that further - adding a signal layer that gives more information and creates cleaner, more actionable entries.
I built a pilot version and put it live. It ran for over 2 years (27 months) on MES futures (Micro E-mini S&P, 5-minute bars). It was profitable after commissions - not spectacular, but promising.
Then, rather than guessing at improvements, I went systematic. Over several months, I designed and ran structured backtests across 6 years of data: testing different stop approaches, exit methods and market regime filters. I used Van Tharp's Market Type framework to understand which market conditions the system actually works in.
The result is what's in this course: a fully specified mean reversion system with a clear edge, tested across 8 distinct market periods, validated on out-of-sample data.
This course is the complete story - the research process, the failures, the discoveries and the final system as it stands today.
This system was not built from one lucky backtest.
It went through four main stages: initial development, a live pilot on MES futures, a structured 6-year testing programme across multiple exit and stop variations and a final out-of-sample validation on unseen data.
What matters here is not just one attractive result. It is the chain of evidence behind it.
Initial Concept & Backtest: developed and presented at Tortoise Capital Research Event
Live Pilot: traded live on MES futures for over 2 years and was profitable after commissions
Further Refinement : 6 years of structured testing across stop logic, exit families and market regime filters
Final selected version: PT-2.5 emerged as the strongest all-round configuration from the exit testing programme
Validation: the final version was then checked on unseen out-of-sample data and passed the practical acceptance test
Robustness: nearby variations also held up reasonably well, which matters more than one isolated peak result
The data and chart set below are results from the final selected PT-2.5 configuration. This version emerged from the broader exit testing process as the strongest balance of performance, consistency and drawdown control.
This is a backtested result, not a live equity curve, and that should be stated plainly. What gives it weight is that it sits on top of a profitable live pilot, a broad multi-year test programme and a final out-of-sample check on unseen data.
Market: MES 5-minute, long-only
Test Period: Feb 2020 to Aug 2025
Trades: 1,092
Win rate: 44.4%
Profit factor: 1.23
SQN: 2.60
Net P&L: $10,398 (per MES contract) or 119.91R
Max Drawdown: $1,532 (per MES contract) or 20.43R
Past performance is not indicative of future results. Trading involves risk.
Exit family comparison across profit target ranges
This chart shows that PT-2.5 was not a random one-off result. Fixed profit target exits were tested across a range of R levels and consistently outperformed the other exit families, with the strongest result appearing at PT-2.5. That is the kind of clustered result you want to see when assessing robustness.
This course gives you the full framework behind the Williams %R mean reversion system, from the original idea through to testing, implementation and live use.

Watch Jeff describe the origin story of the Williams %R indicator, its refinements over time and how he developed it into a mean reversion system. The webinar was originally delivered to the Financial Engineers & Quants Meetup Group in London on 16th April 2026 (25mins).
The course gives you the complete system knowledge.
When you're ready to implement it you can build it yourself in your preferred platform or we'll be offering three levels of subscription for TradingView.
If you'd prefer another platform please let us know by completing this form or contact us.
✅ You're a serious trader who wants to understand a system, not just follow signals blindly
✅ You trade or want to trade futures (especially ES, MES, or similar instruments)
✅ You've tried indicators and systems before but want to see the full research process behind a real one
✅ You want a systematic approach that reduces emotional decision-making
✅ You're interested in eventually automating your trading
This is NOT for you if:
You're looking for a "set and forget" magic system with no understanding required
You want guaranteed profits
You're a complete beginner to trading (some familiarity with technical analysis assumed)

performance data and research findings
lifetime access and future course updates
For this intake, I'm also including a live group Q&A / implementation session so you can ask direct questions and get clear on how to apply the system in practice.
For anyone who wants a little extra context, here is a conversation Jeff had with Larry Williams himself, included as useful background and added perspective.
You've got questions. We've got answers.
Some trading experience is assumed - familiarity with charts, indicators, and basic concepts like entries and exits. You don't need to be a programmer or a quant, but complete beginners may find some sections challenging.
No. The course covers the system logic completely. The TradingView tools (subscriptions available separately) let you implement it without any programming. If you'd like an implementation on Tradestation, MultiCharts or another platform please let us know by completing this form or contact us.
The system has been tested and validated on MES 5-minute futures. The concepts apply broadly to mean reversion trading, but we can only stand behind the specific implementation as tested.
Every course purchase includes 1 month free access to the Williams %R signals indicator on TradingView. The trial can be initiated at any time (it can start as soon as you sign up or you can wait for a time suitable to you). After the trial, it's $40/month if you choose to continue.
• Modules 1-3 are available now
• Module 4 is coming in the next few days
• Modules 5-6 will follow shortly after
Yes - the full system logic is covered. What isn't provided is the source code (Tradestation/MultiCharts EL or TradingView Pine Script). The TradingView tools are available as separate subscriptions if you want a plug-and-play implementation or contact us if you'd like an implementation on Tradestation or MultiCharts.
