It might be due to FOMC minutes that the market is typically less ‘nice’ to trade. The night saw many signals but most came with wide stop losses that rendered the trades not tradeable as it would offer very bad risk to reward ratio. They did work out at the end but it is easy to speak on hindsight.
At the end of the session, the Mini ES offered 4 trades that were fitting to the parameters and all 4 came out profitable.
