Hello,
I am currently using
Metatrader 4 and the fibs begin a 0 and extend to 100 (if you didn't know already

. What I need some clarification on is where to begin the extension for a buy or sell retracement. For example, the trend is heading down, there is a corrective retracement to 62% then it heads down again. Would I place 0 on the fibs at the High and extend down or would I begin by placing 0 at the Low and extend up. The same question applies to the opposite long trade.
Advice much appreciated,
Regards,
Dave
