Already managed to call the top with prior published chart but look here at the comparison with GBP/USD.
Two charts are pretty much inverses of each other up until that long vertical arrow shown.
Since then GBPUSD has recovered nearly all of its losses however FTSE has only retraced a fraction of the gains made in the same time frame. I think a correction will come.
Theresa May set to meet Trump this week and aiming to get a trade deal in place very soon. Could spike sterling further and exaggerate the difference further.
