FTSE looks to be entering a decisive area of intention. Multiple overlapping waves signify a diagonal structure which can only occur in waves 1 or 5 of an impulse or waves A or C of a 3 wave correction.
The support line going back to July 2017 has been broken a number of times and a solid close below 6870 would suggest a very bearish scenario.
Alternatively a rise above 7050 would suggest a corrective rally.
The US markets are possibly entering wave 3 of 3 in their own decline, if they fall heavily next week FTSE will follow. Good Luck
