Identify each tracked coin's 20-day support and resistance and contextualize its move against a combined BTC/ETH benchmark bias
Answers where a coin sits within its trading range and whether the broader crypto market backdrop supports or fights that position. It reads up to 220 daily candles for each tracked coin and for BTC and ETH (the crypto benchmarks, until dedicated ecosystem-taxonomy data lets ATLAS pick a single benchmark per asset the way the equity version does by sector), computing 20-day support and resistance, distance to each, and a combined benchmark bias from BTC and ETH agreeing bullish, bearish, or otherwise neutral. Labels each coin's range position against the benchmark bias, such as near support with the benchmarks in agreement or near resistance with them opposed. Use it to read a coin's range position against the broader crypto tide rather than in isolation.
Support and resistance, plus a market-context filter - and an honest account of how much of this is convention rather than theory.
SUPPORT AND RESISTANCE AS COMPUTED HERE are simply the lowest low and highest high of the trailing 20 days, with the distance from the current price to each. That is a well-defined, reproducible statistic, and it is worth separating from the FOLKLORE around the same words. The traditional claim is that prior extremes attract or repel price because participants remember them. The mechanisms offered are behavioural - anchoring, and a disposition effect in which holders who bought near a prior high sell to break even as price returns there - and there is a body of academic work testing whether such levels have predictive content, with mixed and generally modest results. The distinction matters: the NUMBER is a fact about the last 20 days; the INTERPRETATION is a hypothesis.
A POINT THAT DISPOSES OF MANY BAD CHART READINGS. A 20-day high is a rolling extreme, so it is by construction a level price has recently reached. It updates every day, and a level that 'held' is often just the observation that a new extreme was not set. Any claim about such a level should specify the window, because a 20-day high and a 200-day high are entirely different objects that look identical on a chart.
THE BENCHMARK BIAS. BTC and ETH are read alongside the coin, and their agreement forms a bullish, bearish or neutral market backdrop. The reasoning is sound and is the strongest part of this analysis: crypto returns are highly co-moving, so an individual coin's range position means less in isolation than it does with the market's direction attached. The same setup with the market rising and with the market falling is not the same setup.
BUT NOTE WHAT AGREEMENT BETWEEN BTC AND ETH IS WORTH. They are strongly correlated with each other, so their concurrence is much weaker evidence than two independent readings would be - closer to one signal observed twice than to two signals confirming. And BTC and ETH are only a market proxy: this analysis reads no ecosystem taxonomy, so it has no per-asset benchmark of the kind the equity version takes from a sector.
A CIRCULARITY WORTH SEEING. Because most coins co-move with BTC, a coin near its 20-day low when BTC is also weak is largely restating the same fact twice. The 'confirmation' is partly mechanical.
The 20-day window, the 220-day history, the setup labels and the bias construction are our own convention.
