i've been exposed to the idea of the need to check e.g. the sector index or the main index such as the all ords or asx 200 b4 you do a trade. that when the main index is going down, it's not advisable to take a long position right. and we should check to make sure it's going up b4 we go long. let me know if i'm wrong. but i'm just not sure how i would practically do this ???? eg. for short term trades should i check that the all ords is also in a short term up trend , or what??
