The Proven Trading Formula I Wish I Knew Sooner
I am about to share the proven trading formula that completely changed my perspective on what it takes to make money in the markets. I did not learn it from a textbook. I did not find it in some expensive online course. I learned it from a former CIA agent named Mike — one of the most remarkable people I have ever met.
Mike was a Navy graduate, a pilot who flew missions during the Cold War, spoke fluent Russian, and worked as a CIA agent in Russia. After retiring from one of the most high-stakes careers imaginable, he started day trading. And what he taught me about expectancy and the profit-loss ratio is something every trader needs to understand — because it strips away all the complexity and reveals the one thing that actually matters.
“You Are Working Way Too Hard”
Mike was extremely intelligent, but what set him apart was his ability to simplify everything. When I first met him and started talking about indicators, patterns, and complex entry logic, he looked at me and said something I will never forget: “You are working way too hard.”
His core philosophy was built on a few brutal truths about the markets:
- Markets are non-stationary. Any predictive model works for a while and then stops. This is the nature of financial markets — they change constantly.
- Markets are basically random. On any given trade, the outcome is close to a 50/50 coin flip. However, indexes have a built-in long bias that gives you slightly better than 50% odds on the long side.
- Win percentage fluctuates wildly. Some months you win 80% of your trades. Some months you win 30%. That is not a flaw in your system — it is the nature of markets.
So if the markets are essentially random and your win rate is going to bounce around no matter what you do, what is the point? That is exactly the question Mike answered with this proven trading formula — and the answer has nothing to do with picking better entries.
The Only Question That Matters
Mike boiled everything down to a single question: How much do you lose when you lose, and how much do you make when you make?
That is it. Not “what is your win rate?” Not “what indicator do you use?” Not “are you trading the right timeframe?” The only thing that determines whether you are profitable long-term is the ratio between your average winning trade and your average losing trade — your profit-loss ratio.
This concept comes from Van Tharp’s work on expectancy, outlined in his book Trade Your Way to Financial Freedom. Mike took Van Tharp’s framework and distilled it into a simple table that changed how I think about every single strategy I build.
The Expectancy Table — The Core of This Proven Trading Formula
Here is the table that Mike showed me. It maps your profit-loss ratio against your win percentage and tells you whether you make money, lose money, or break even. Study this carefully, because once you understand it, you will never look at trading the same way again.
| Profit-Loss Ratio | Win Rate Needed to Break Even | Key Insight |
|---|---|---|
| 1:1 | 50% | Coin flip = breakeven (minus commissions you lose) |
| 1.5:1 | 40% | Lose more often than you win, still profitable |
| 2:1 | 33% | Win 1 out of 3 trades and break even |
| 2.5:1 | 29% | Nearly 3 out of 4 trades can be losers |
| 3:1 | 25% | Only need to be right 1 in 4 times |
| 4:1 | 20% | 80% of trades can lose and you still break even |
| 5:1 | 17% | Massive safety margin — almost impossible to fail |
Look at that 2:1 row. If your profit target is twice your stop loss, you only need to win 33% of your trades to break even. That means you can be wrong on two out of every three trades and still not lose money. Add even a small edge — bump that win rate to 40% or 45% — and you are making serious money.
Now look at 5:1. You could lose 83% of your trades and still break even. That is the power of this proven trading formula. It does not require you to predict the future. It requires you to manage your risk properly.
How Mike Traded — Simple and Profitable
Mike’s actual trading method was almost shockingly simple. His entire approach:
- Entry signal: Just divergences. Nothing complicated. No stacking five indicators on top of each other.
- Profit-loss ratio: 2:1 on average. His profit targets were always at least twice his stop losses.
- Trading window: The first two hours of the trading session only. After that, he was done for the day.
- Mindset: He never cared about any individual winning or losing day. His exact words: “The math works in my favor. At the end of the year, I will be positive.”
And he was right. Mike made money consistently, year after year. Not because he had some magical entry signal. Not because he could predict where the market was going. Because the math — the expectancy — was always working in his favor.
The Coin Flip Experiment That Proves It
If you still think you need a brilliant entry to make money, consider this. Mike and his trading group ran an experiment. They literally flipped coins to pick the direction on 30 options trades. Heads meant buy calls, tails meant buy puts. Completely random entries.
Then they focused exclusively on risk management — their exits, their position sizing, and their profit-loss ratios. The result? They made a 100% return in four and a half months. With random entries.
Let that sink in. A group of traders doubled their money in under five months without having any edge on entries whatsoever. The entire edge came from how they managed the trades after entry. This is the proven trading formula in its purest form — the exits and risk management matter infinitely more than the entries.
How I Apply This Proven Trading Formula to Breakout Trading
When I heard Mike’s philosophy, something clicked. Because breakout trading solves the direction problem that Mike’s coin-flip experiment deliberately ignored.
Here is how the proven trading formula integrates with my breakout approach:
- Breakout entry solves direction. When price breaks out with momentum, the direction is already declared. You are not guessing — you are following the momentum that is already there. This is an inherent advantage over random entries.
- ATR in the entry calculation ensures volatility is present. Breakout entries that incorporate the Average True Range only trigger when the market is actually moving. No volatility, no entry. This keeps you out of dead, choppy conditions where the profit-loss ratio collapses. If you want to understand why ATR matters so much, our guide on the best trend indicator breaks it down with a full strategy.
- I always check the average win versus average loss ratio. Before any strategy goes live, I look at the historical data. I want to see at least a 2:1 ratio between average winning trade and average losing trade. If it is not there, the strategy does not make the cut.
One of my recent strategies had an average win-to-loss ratio of 5.65:1. That means I could drop all the way to a 15% win rate and still break even. Think about that — only winning 15 out of every 100 trades and not losing money. That kind of safety margin is what lets you sleep at night when the inevitable losing streak hits.
The Profit-Loss Ratio as Your Safety Belt
I use this ratio as the final checkpoint for every strategy I develop. In my hedge fund work, this is the last filter before a strategy gets allocated real capital. You can have a beautiful equity curve, impressive backtested returns, and strong statistical significance — but if the profit-loss ratio is weak, that strategy is fragile.
A strong profit-loss ratio is your safety belt. When markets shift (and they always do), your win rate will drop. That is guaranteed. The question is: does your strategy survive the drop? If you have a 2:1 or better ratio, you can weather significant declines in win rate and still come out profitable. If you are running a 1:1 ratio, even a small dip in win rate puts you underwater.
This is why I encourage every trader in our community to stop obsessing over win rate. Win rate is the metric that makes you feel good. Profit-loss ratio is the metric that keeps you in business. If you are just starting out with breakout trading for beginners, learn to evaluate this ratio from day one.
Keep It Simple — That Is the Whole Point
I want to close with something Mike said that has stuck with me for years: “Keep it reasonably simple. Sometimes thinking about what you could remove gives more results than thinking about what you could add.”
Making money in the markets does not need to be complicated. A simple breakout entry, a solid profit-loss ratio, and basic risk management. That is the proven trading formula. It worked for a former CIA agent trading divergences for two hours a day. It works for me running thousands of breakout strategies across global markets. And it even worked with a coin flip.
A friend of mine trades a strategy that is literally “enter on Friday, exit on Monday.” He built it from Excel spreadsheets. And he makes a lot of money with it. Not because the entry is genius. Because the math works.
Stop adding complexity. Start looking at your expectancy. Check your profit-loss ratio on every strategy you run. If it is below 2:1, either fix your exits or find a different strategy. That one change — focusing on how much you make when you win versus how much you lose when you lose — is worth more than every indicator, pattern, and guru prediction combined.
