GBPUSD -- 1.3585
Since 01jun21 Sterling has been trading in a medium term downtrend against the Dollar. The spot movement could be described very well by a channel. After two weeks of soaring Sterling the currency pair is nearing the upper descending trend line of the channel now. With respect to a quite high RSI and the fact that the last two weeks have been holidays with lower liquidity for the most of the time the move in spot could be overdone.

EURGBP -- 0.8342
The British Pound looks stretched agains the Euro either. In particular, the move from 0.8380 to 0.8336 since the beginning of the year looks exaggerated. To see the next real level of support we have to switch to a weekly chart. At 0.8282 was the low of the last year. If you thing about to play the currency pair from the long side you could use that level with a tight stop placing. On the hand you are covered against a quick escalation to the downside. On the other hand you do not lose too much if spot moves quickly back to its recent 0.84/0.86 range.
Good luck,
