The Copper/Gold Ratio: An Overrated Macro Signal for Bitcoin
The copper/gold ratio is sold as a macro and Bitcoin signal. What it actually measures, where it fails, and why a viral "Bitcoin cycle" indicator built on it has look-ahead bias.
Opening Range Breakout: Real Strategy, Oversold Story
ORB is sold as the holy grail of intraday trading. What the strategy really is, why the viral result misleads, and what makes or breaks an honest ORB backtest.
Filters: A Regime Gate Is Not a Magic Switch
A filter that rescues one strategy can strangle the next. We ran 189 filter combinations on crypto — and exactly one survives the strictest overfitting test. What that reveals about the 200 WMA, ATR, Altcoin Season and the Bullmarket gauge.
The Signal Layer: Read the Market Before You Trade
A good strategy in the wrong market phase still loses. Six free tools give you the market's temperature — Arena Pulse, macro regime, on-chain, the Bitcoin cycle, sentiment, and the signal traffic light. All share one honest trait: they describe the present, they don't predict the future.
Why Experts Forecast Worse Than Chimpanzees
A chimpanzee guessing at random beats educated experts on fact questions — and forecasters on predictions. That's not a punchline but the finding of several of the most-cited studies. Why it happens, what Michael Burry has to do with it, and why a real prediction needs two things: a what and a when.
Triple Strike Reversal — A Strategy Not Made to Stand Alone

"Bitcoin is going productive" — they say. Wrapped BTC brings BTC into DeFi. How big is it really, who dominates, where are the catches? A sober map.
On a Short Leash: How the US Pushes Its Debt to the Short End
The US Treasury increasingly funds itself with short-dated T-bills. That lowers cost today — and builds rollover risk for tomorrow. A methodical read on the mechanics behind the headlines.
When Fees Kill a Strategy: Why We Benched Our Second-Most-Popular One
Our backtest engine used to compute returns before costs. We built a net-of-cost layer that re-prices every fill at a realistic fee — and it flipped our second-most-popular strategy negative after fees. Here is the math, the numbers, and why "beats buy-and-hold" is half a truth until you pay the fees.
AI in the Drug-Discovery Race: Shovels, Bets, Giants
Asking which company is well-positioned in the AI drug-discovery race is really three questions at once. We sort the field soberly into shovels, bets, and giants — and show which layer earns regardless of any single trial outcome.
We Rebuilt Our Worst Strategy Correctly — It Worked — and Cut It Anyway
Our Bollinger Squeeze strategy lost to Buy & Hold by double digits on crypto. Before deleting it, we rebuilt it to the modern standard (TTM Squeeze). The rebuild turned positive — and we retired it anyway. Why "it works now" isn't enough.
