Bug Report: Trendline snapping issue in ForexTester Online

Feature Request

Hello,

I would like to report a bug in ForexTester Online. When I try to draw a trendline, the line snaps only to fixed angles (0°, 90°, 180°), and it is impossible to make fine adjustments to the angle.

Interestingly, if I update Chrome to the latest version, the trendline behaves normally and I can adjust the angle freely. However, this is very inconvenient since I have to update the browser each time to avoid the bug.

Could you please investigate this issue and provide a fix?

OS:Mac
Google Chrome version 139.0.7258.128（Official Build） （arm64）

Thank you.

    Hi @User! Thank you for reporting the issue and providing detailed information.

    From your description, it seems like ForexTester Online is interpreting the Command key (Ctrl equivalent on Mac) as being pressed while placing trendlines. This causes the line to snap to fixed angles (0°, 90°, 180°).

    This can happen due to:

    A stuck or “virtual” modifier key in the browser.

    Conflicts with Chrome extensions that intercept keyboard input.

    A browser-specific issue, as you noted that updating Chrome resolves it.

    For now, the simplest workaround is to update Chrome to the latest version, which seems to fix the problem. Additionally, try disabling extensions temporarily to see if one of them is causing the key to stick.

    We’ll continue investigating this to see if there’s a way to prevent it from happening in older browser versions.
