Long-form writing by Dr. Ken Long, organized by the four stages of the Trading Loop — Plan, Prepare, Execute, Assess.
Plan (11)
Build the written plan you can trust when pressure hits — strategies, regimes, goals, the system on paper.
Plan for disciplined market work
Every trading plan begins with a blunt question: what do you do when pressure hits and you have no map? Without one, you improvise. You size up at the moment you should freeze, chase a move that has a
Trading Strategy: How To Build One That Fits

Rule Based Trading System Fundamentals And Build Process
Every rule based trading system starts with the same premise: if you define the conditions clearly enough, the decision makes itself when those conditions appear. You remove the guesswork, trade the p
Understanding Different Types of Trading Styles

Market Regimes: How To Identify And Trade Them

Market Regime Classification for Smarter Trading Decisions
Most traders have watched a strategy that printed money for weeks suddenly start bleeding capital. Nothing changed in your rules, your indicators, or your discipline. What changed was the market itsel

S&P 500 Trend Following Backtest: What Matters
Most traders who run an S&P 500 trend following backtest make the same mistake. They test one moving average crossover on twenty years of data, see a nice equity curve, and assume they have found
Prepare (4)
Finish the work before the screen lights up — sizing, risk, marked levels, the honest physical and mental check.
Prepare for disciplined execution
Preparation is the real work of trading, the structure that holds everything else together. When you sit down at the open with a written plan, a marked chart, and a clear head, you are trading. When y

Position sizing is the single skill that separates traders who survive from traders who blow up. You can have the best entry signals on the planet, but if you risk too much on one trade, a short losin
Risk Per Trade: Position Sizing And Drawdown Control
Every trade you take carries a cost if it fails. That cost is your risk per trade, and it is the single most important number in your trading plan. If you define this number before you click t
Execute (7)
Apply the plan under live pressure — manage the position by rule, protect open profit on the way out.

Manage Winning Trades With Clear Exit Rules

Why You Can't Take the Small Loss — and What to Do About It
Standard work for the trader who keeps finding themselves here.
Assess (7)
Study your own marks with the rigor you study the market — journal, R-multiples, expectancy, CAR25.
Assess for trading review discipline
Every trade leaves a mark. Some marks show up plainly in your account balance, and others hide quietly in your habits, your hesitation, and your timing. The trader who keeps growing and the trader who
Trading Journal Guide For Serious Traders
Most traders lose money for the same reason most dieters regain weight: they never build a feedback loop between what they do and what they measure. Your trading journal is that feedback loop,
Review Trading Performance With A Practical Framework
Most traders check their profit and loss number at the end of the week and call it a review. That is not a review. That is scorekeeping, and it tells you almost nothing about what you are actually doi
R Multiple Trading: Measure Risk And Performance
Most traders obsess over dollars won or dollars lost. That metric lies to you.
Win Rate: How To Calculate And Use It
Your win rate tells you one thing clearly: out of the opportunities you took, how many did you actually win? Whether you trade financial markets, close sales deals, or compete in ranked games, this si
Profit Factor: How To Measure Trading Edge

CAR25 Trading: Risk-Normalized System Evaluation
Most traders pick a system based on its compound annual rate of return and call it a day. That single number tells you how fast the account grew, but it says nothing about the pain you endured to get
Backtest discipline (8)
Cross-cutting — every stage relies on honest historical evidence. Bias detection, slippage, overfitting, benchmarks.
Backtesting Trading Strategy Fundamentals And Process
Every professional trader reaches a point where a strategy either earns its place in the book or gets cut. The difference between those two outcomes is almost never about the idea itself.
Backtest Failure: Why Strategies Break Live
Your backtest looked bulletproof. The equity curve climbed at a steep angle, the Sharpe ratio was impressive, and every metric screamed "deploy this now." Then you went live, and the strategy bled mon
Lookahead Bias Trading: How To Spot And Prevent It
Every backtest you have ever run carries a hidden assumption: that the strategy only knew what it could have known at the time. Lookahead bias in trading occurs when your model, script, or dec
Overfitting In Machine Learning: Causes And Prevention
Every machine learning model you build faces a fundamental tension: learn the training data well enough to be useful, but not so well that it memorizes quirks and noise instead of real patterns.
Survivorship Bias Backtesting: Building More Reliable Tests
Your backtest looks profitable. The equity curve rises steadily. The Sharpe ratio sits well above 1.0. Everything points toward a strategy worth trading live. Then you deploy it, and the returns vanis
Random Portfolio Benchmark: How To Measure Skill Fairly
Most traders compare their returns to a single index and call it a day. The problem is that a single index carries built-in biases toward certain sectors, market caps, or weighting schemes. When you m
Slippage In Trading: Causes, Costs, And Control
Every trade you place carries an expected price. The price you actually receive can differ.
Slippage Model Backtest Essentials For Realistic Results
