The trouble with Lira is you cannot predict it properly against either the Euro or Sterling it has a mind and obviously(Turkish Government) of it's own, it was not generally expected to cut interest again but they did! A rate cut by the Central Bank has obviously helped devalue the Lira thus the exchange price is going up but this will stable again especially when other currencies like Euro and Sterling devalue their currencies early next month with interest rate increases so imo now up to Thursday this week is the time to exchange to take advantage of this high rate as it will not last much long past this coming Thursday when the BoE put interest up as expected especially after the latest inflation increase news in UK.
