Against unstable markets, wild price swings, and constant rises and falls, the answer is offered like this. When GBP/USD dropped every week to extreme levels from 1.2900's to 1.1900's, GBP trading was dropped on the 2nd week of constant drops. When AUDUSD broke 0.7000's and dropped every week to extremes without correction, AUD trading was dropped.
Markets are in melt down mode, EURAUD bolted higher 2000 pips this week, EURNZD 3800 pips. GBPUSD began the week in deep oversold at 1.2200's and now trades 1.1400's. USDJPY above 110.00's, a price doesn't exist. AUDUSD still falls straight down at 0.5500's from the 0.7000's break. GBPCHF at 1.1100's doesn't exist on record. EURGBP at 0.9200;s doesn't exist on record. The list goes on.
Then what I term ghost prices exist. EUR/NZD above 1.7600's, EUR/AUD above low 1.6000's, USD/CAD above 1.3000's and ths list goes on. A phantom price cannot trade on our accounts by any rationality, not by our models and not any reasonable standards. And never to damage successful trading over decades.
Its insanity to believe profits are earned in melt down markets and done by skill especially against deeply oversold / overbought and not when bottoms are tops are yet to establish.
