What is wrong with the MYR price in luno for BTC right now?

It is trading at all time high and with the conversion it should be trading at 473k myr right. Why is it trading at 462k myr in luno while hata is at 470 smtg? I just bought tons of BTC since I think there might be an arbitrage opportunity. Can someone with knowledge explain? The price in USD in luno is correct though.
