The best time beside trading in a trending price action to trade is by having PATIENCE and waiting for a pair to make a breakout of a of a confluence area, either up or down. Wait for to close out of this area, for safety. This is not a time to anticipate, but to wait for close of . Noted on USDJPY 15 mn chart are area's of narrow side ways or confluence areas (orange oval areas/rectangle). These MOSTLY happen at levels.
*Whatever time-frames that yo trade, unless pair is in a TREND, wait for breakout of a tight price action area, before entering a new trade. If you trade trending pairs, move on to a pair which is showing momentum, not ranging PA. Most people have mentally of I am in front of computer & want to trade NOW, so they trade... this is risky behavior!!
