This type of strategy is fine for getting your bearings & setting out your stall, but still requires quite a bit of work to put the odds firmly in your favor.
Looking across your 5 minute timeframe, there were multi signals for the most part of yesterday's New York session. But they were printing underneath a confirmed lower top resistance zone off recent session highs.
During the Tokyo shift, prices were printing lower high's & that signal you executed on the GBP occured late into the Tokyo shift, before London woke for today's session.
I'm not saying all such signals need to be avoided, but due care is certainly required before London clears it's throat, especially under current 24hr price action conditions.
We've got a lot of important news being released this week, & with all the recent bid action on this currency, players will be jostling for some value positioning.
