GBPJPY
On 1 of my brokers, we have the market opening at 2200GMT on 01/Nov/09 and they represent the low as 145.79.
However, on another broker using central european time, they open at 2300GMT (server time 0000MGT) and the low was 100pips away at 146.80! Their reason for this is that “If we started at 10pm (GMT) this would be 11pm (server time) so we would have only an hour candle for the day.”
I can fully understand this but the first broker merges the Sunday night data into their next day’s candle. I can’t really say who’s right in this method as both have their pros and cons but I can certainly say that not representing the low anywhere in the 2nd broker’s data will cause problems. Normally, I wouldn’t notice but in this instance it clearly throws out one of the methods I use.
