GBPCAD: Crazy idea

Analysis over the past 20 days with a buy/sell based on the previous day's mid point.

BUY If price at 3pm (UTC+8) is below ytd's mid point
SELL if price at 3pm (UTC+8) is above ytd's mid point

3pm (UTC+8) = London opening

Disclaimer: please do you own analysis ... this was done past midnight after a couple of wines.
