hey @haejin, i think i have a temporary workaround for your mouse issue.
In the browser, hit F12 to open the developer tools panel. In that panel, select the 'console' tab and paste this in and hit enter:

$('td.chart-markup-table.pane')[0].setAttribute("style", "cursor:none");

you can then close the developer tools panel with F12 again. this will hide your mouse cursor whenever its hovered over the candlestick chart panel and you can just use the crosshairs. The effect will go away if you refresh the page or close the browser tab. This code will also only work on tradingview.

I hope this helps you like you've helped us and i wish you MASSIVE profits!!!
