USDMXN buys from partial/full imbalance fill

Im looking for a strong rejection at or near wkly opening price to push price back down to fill initial bullish imbalance candle left near recent low. Im looking for an entry near 19.8135 area once rejection is confirmed in this zone. Otherwise, if price continues for complete imbalance fill, we will look for even better entry at wkly low for bullish move back to the upside.
