I asked this question before and I will ask it again… I trade mostly 4hr and dailies, I usually trade 1-6am est (primarily the London session). What do most people look at EST charts or GMT, I know it may seem silly but there is a difference in the candle OHLC, the difference could make a shooting star on one look like a non-reversal candle… you guys get the point so what do most people look at!!!
I use 3 different time frame charts Oanda (est), North Finance, GMT+3,
& Alpari, GMT+2.
But my candlestick TA is done on Oanda.
I use mt4 which is GMT (london) Im est (-5gmt) but we are in daylight saving time now so I am really gmt-4 it gets really confusing!!! but anyway mt4 is set at GMT
As long as you are consistent, it doesn’t matter which timezone your charts are based on.
