How long each bar covers. Use a number of minutes (1, 5, 15, 30, 60, 240), a letter for daily/weekly/monthly (D, W, M), or an N-trade tick bar (100T, 500T). See ChartResolution for the full list.
How long each candle/bar on the chart should cover. Three families of values are supported:
Intraday (minute bars) — 1, 3, 5, 15, 30, 45, 60, 120, 180, 240 — the number is the bar's length in minutes (e.g. 5 = five-minute bars, 60 = hourly).
Daily and longer — D / 1D = daily, W / 1W = weekly, M / 1M = monthly, 3M / 6M / 12M = three-/six-/twelve-month bars.
Tick-based — 1T, 5T, 10T, 25T, 50T, 100T, 250T, 500T, 1000T — bars that close every N trades instead of every N minutes. Useful for fast-moving markets where time-based bars are too noisy.
1, 3, 5, 15, 30, 45, 60, 120, 180, 240, D, W, M, 1D, 1W, 1M, 3M, 6M, 12M, 1T, 5T, 10T, 25T, 50T, 100T, 250T, 500T, 1000T "D"
