Pin bars chart patterns on 4 hour, daily & weekly time frames are highly reliable & safe to enter new trades. Like all chart patterns, you don't jump on all chart patterns, but be picky and just pick the BEST ones. What are the best chart patterns? Ones that happen at major Area, Price Points, Psychological numbers (more zero's in a price action number the better; like 1.45000 the price action chart number of latest noted chart pattern), indicator (make sure they happen in overbought > 70 ( ) top areas or oversold < 30 ( ) bottom areas on indicator. If you utilize any EMA's or MA's like my noted 8 & 21 they did a cross, which is another positive for a price action . Still has room to fall this next week. Next major on this GBPUSD 4 hr chart is around 1.43125ish, price action now is 1.43508.
Price action is number one, money management & understanding language of CHARTS. Wish you the best.
