GBP to USD:
The GBP/USD D1 chart once again challenges the lower resistance level. Although the current trend is still in a downtrend, it can be found that the price of the D1 chart is in a consolidation state at this stage and the price has touched the lower support level, so you can try to be bullish.
The H1 chart can also see that the price is currently blocked by the support below. The RSI indicator also shows that the price is already in an oversold state, and it can be appropriate to go long and catch a callback. There is no way for the price to continue to fall, and it will inevitably continue to fall after a callback.
In the short-term, you can choose to do more at a low level, and the profit point can be set with Fibonacci backtesting. In the long-term, you can wait for the lower support level to be broken through to find a profit point with the Fibonacci extension line.
All transactions involve risks, the above analysis is for reference only. When placing an order, be sure to set the lot size and remember to set the stop loss.
