ChartHawk - Key Levels + 8EMA Bias [Free]

Premarket and prior-day levels, drawn clean, with a daily 8EMA bias tag.
Every session opens with the same four lines that matter: the premarket high and low, and yesterday's high and low. This plots all four automatically and keeps them on your chart, so you are not redrawing levels every morning.
How to read it:
- Green marks a high (PMH / PDH). Red marks a low (PML / PDL).
- Dotted lines are premarket. Solid lines are prior day.
Colour tells you which side of the range you are looking at; line style tells you which session it came from.
The tag in the corner reads LONG or SHORT off the daily 8EMA - a quick top-down read on whether the name is trending with you or against you before you take an intraday setup.
Premarket levels are pulled from the extended session, so they populate whether or not you have extended hours turned on for your chart. Prior-day levels use confirmed daily data and do not repaint.
Alerts - five built in, all confirmed-close only, so a wick through a level cannot trigger them:
- Closed above premarket high
- Closed below premarket low
- Closed above prior-day high
- Closed below prior-day low
- Daily 8EMA bias flipped
Settings: session window, timezone, EMA length, tag size, colours, and price labels are all editable.
Educational tool only. Not financial advice, no signals, no trade recommendations.
