How could the charts be exactly the same when each market has its own buyers and sellers. Prices are determined by the balance of supply and demand in that market. so naturally, there are differences due to different order books.
Each market also has different liquidity. Markets with high volume are usually more stable, but in smaller markets even a few trades can create strange looking candles.

There are actually many factors that affect this. This is also often due to candlestick data sources, some markets use the Last Price, while others use the Market Price or Index Price. This makes the opening, high, low and closing prices not the same.
In reality the movements usually tend to be similar but the details of the candlestick are not 100% identical.
