The price reached the bottom of a downtrend, but since we can't really talk about a bottom of a downtrend, it will be a risky trade, because trend is our friend, right? and we should trade in the trend direction. So if we take a look at the RSI combined with the bollinger bands, we see that the price reached the low level on all timeframes. We will wait until the price breaks the 15 min downtrend of the leg and retests the previous high of the 15 min. We may enter around the 0.89500 level after the retest was made, at the closure of an engulfing bar which will break the previous ones. TP1-0.89870, TP2-0.90300, SL-below the low of the 4h, for a safe one.(around 0.89030), or a tight one, below the higher low that will be created, i'd say 0.89230 is a good one.
