It did not fall to 13 august level in London when i took a gamble top up @ 1.7p but near @ 1.8p showing a 25% spread the difference in published prices about 17%.
I sold back that slice on sharp rise to 2.3p before end of month , someone posted should of sold the lot on that spike and in hindsight .
Not sure if its a worse situation now so not brave enough to try that again .
The odds to much in favour of the brokers with the spread.
