I want to ask... Why does each h4 candle differ in the GBPUSD pair. Is it because different brokers have different candles? The one in the middle is Exness, the one below is FBS, and I forget which broker the one above is.

@ Brahmana:
That's right, the candle shape from each broker can be different, because the server opening hours of each broker can be different, so the open and close prices of each candle can also be different.
@ Surya:
The price of the server does follow market prices, but if the server opening hours differ for each broker, then the open and close prices of each candle from each broker will be different. After all, a candle consists of the open, high, low and close prices.
For news on the same pair, the impact of price movement on all brokers will of course be the same.
