Previous gap was successfully closed but at the same time, several poor lows were created on the way up. Sellers might have some unfinished business at 164 GBp level and could continue opening short positions aggressively till 156 GBp level. In case of even small panic, we can expect retest of 149 GBp and 137 GBp levels.
Selling in LSE:FXPO ended on Monday and since then, buyers started to pile on moderately. In case of continues recovery above 163 GBp, potentially we could see a gap closure at 170 GBp.
