Usdcad retracement buy , trend ends or continue

Ive taken some buys at the lower low area just made , this could be just retracement or it could be the beginning of a change in trend , the markets just made a monthly lower low so a major retracement swing can be possible. Gonna watch how the markets react around the red highlighted area.

If i decide to take sells in the red sell zone ill be looking for doji, and any other exhaustion candles on the daily in that area
