If I were building a strategy around “buy after a daily close above resistance,” I’d need to know when that day ends.
A candle built around midnight UTC and one built around midnight UTC+8 collect different slices of the same market. A rally can finish inside one day's candle and spill into the next on the other chart. The last trade in each window can differ, so one daily close can clear a fixed resistance level while the other stays below it.
Binance Spot supports both ways of building daily candles. UTC is the default; a different candle time zone changes the intervals themselves. Merely relabelling the clock beneath an existing chart wouldn't do that.
That makes the closing hour part of a daily strategy's entry rule. It determines both the price being tested and when the signal becomes available. A backtest built on UTC days and an alert built on UTC+8 days can disagree without either having bad prices. Matching the coin and the “1D” label still leaves that part of the rule unspecified.
