Reading the ARM chart
US stocks trade from 9:30 am to 4 pm New York time, and news outside those hours shows up as a gap between one candle and the next. Earnings reports, usually four times a year, often cause the biggest moves on the ARM chart. Daily and weekly candles show the broader trend; intraday charts help with timing. The 50- and 200-day moving averages are widely watched on stock charts like this one.
Frequently asked questions
Is the ARM chart free?
Yes. FreeCharting is free, and Arm Holdings data comes from a provider you connect with your own key. Twelve Data, Financial Modeling Prep and Alpaca all have free plans.
Why does the ARM chart ask for an API key?
Market data is licensed, so providers ask for a key even on free plans. Your key is saved only in your browser and sent only to that provider.
Is the ARM price real-time?
It depends on your data plan. Many free plans give end-of-day or delayed prices; paid plans and brokerage keys (for example Alpaca or Tradier) can give real-time data.
