Singapore market is open, when trading in our market starts.
European market (UK, Germany, France ..) opens around 12.30 pm our time (during winter day it shifts to 1.30 pm our time).
Foreign markets just impact the sentiments in our market (and fool many novice traders), but after few moements market takes its own direction based on the demand and supply equation.
All global markets get main clue from last action in US markets. Sometimes, Asian /European markets start anticipating what might happen in US tonight and follow different pattern.. but by that time, our market is closed (when It is 10.00/11.00 oclock in European market).
Happy Trading.
