DislikedWhat a beautiful image ! Look similar to me. They will not be exactly the same because of different bidding on basket pairs. But looks very close and hence can be traded.Ignored
EURCHF rate is offered from liquidity providers (major banks), it is not calculated based on EURUSD and USDCHF rates.
EURUSD and USDCHF rates are also offered from liquidity providers, and so on.
A broker will either average the rate received from liquidity providers, or take maximum bid/ask or use any formula to show its bid/ask price for a pair.
You can notice the differences in a same chart at different brokers because they use different liquidity providers or just being market makers.
No guts, no glory
