Altcoin breadth tells you how many coins are above their 200-day line, and the answer depends on which coins are counted. Since 2018 the 100 most-traded came out ahead on 72% of days, recently 70% against 40% for all altcoins. Which number applies to the coin you hold?

The band softens the crash in Bitcoin, Ether and stock indices. In half of the large altcoins it brakes too little, and in gold not at all. 35 coins, three indices and gold, tested.

Ichimoku is usually traded with 9, 26 and 52 and with the rule "only buy above the cloud". Both were tested on crypto from 2018 to October 2026. The cloud rule lowered the result on all ten of today's largest coins, and on bitcoin and ether the traditional numbers did no better than randomly drawn ones. What that means for your settings.

The anchored VWAP strategy draws an average-price line from a starting point you pick, such as the last low, and buys while price stays above it. Its result depends on that starting point. On six years of Bitcoin, none of five common anchor rules placed the line better than chance, and the 52-week low did worse than 99 percent of random anchors. Why that happens, why the charts still look convincing, and what to use instead.

Screeners label altcoins "uptrending vs BTC" and stop there. We measured what followed the label across 370 pairs and 458,000 days — and what followed any day.

Young coins without 200 weeks of history skip the 200-week filter automatically. We tested the obvious fix across 207 coins — it made everything worse.

25+ strategies, and the honest question is never "which is best?" It's: which fits what, and when? Four truths that run through the whole library — timeframe decides, "beats B&H" often means losing less, win rate isn't profit, and fit beats breadth.

We ran the same RSI/SMA crossover across the top 50 coins and the top 50 US stocks — identical rules, identical window. On crypto it beats the buy-and-hold benchmark 80 % of the time; on stocks, 4 %. Why a trend-following strategy works in one market and bleeds in the other.

The 200-day line is the most-cited trend filter in markets: invested above it, out below it. We tested it as a standalone strategy across 110 assets. The result is not one-size-fits-all — on crypto it beats Buy & Hold on return AND drawdown AND Sharpe; on index ETFs it gives up almost no return while nearly halving the drawdown; on single stocks it works poorly. An honest map of where regime timing pays and where it doesn't.

A new strategy is live: two configurable EMAs cross — BUY on the upward cross, SELL on the downward cross. Default 9/21, faster and more tunable than Golden Cross. Plus optional volume- or price-confirmation filter to fight whipsaws.

Every few months crypto media announces a Bitcoin Golden Cross. But does the signal actually work? We tested it against historical data — on daily and weekly candles. The answer is more nuanced than the headlines.

A new strategy is live: Supertrend, one of the most popular indicators on TradingView. ATR-based bands that ratchet with the trend — the stop only moves in trend direction, never back. Default 10/3.0 with Wilder smoothing. Pro+.
