Use GMT time (0)
DPP and S1/R1 are the ones I pay attention to.
Look at EU chart of today as an example
1) Find one for trading (or charting) that open/close the 240M candle @ 08H00 GMT ( LDN open) Trading activities pick up then and you don`t want to trade a 240M strategy with a set of charts that are busy rolling over at that time.
2) Run a second MT4 platform with different broker time for 240M candle open/close and compare signals
3) Split your trades in half and trade first and/or second signals
Thanks for the opportunity...Ignored
or a broker that opens a new candle at NY close as thats the end of an official trading day ?
