Long IdeaEuro/US DollarFX:EURUSDk45bryantWhen this occurs, it is not uncommon to see price approach the line, and "throw a spike" over the line. At other times price might approach but not quite reach the previous high or low. This tells you that the current price is already on the correct side. You will therefore expect the price to "bounce down” or “bounce up" as the case may be. This will most often occur around the time of the London open. You should recall that this is likely to be part of the market makers aim of keeping traders trapped. If they've already made a high for instance, and there are positions trapped here then they will not want to push price above it again but will then approach it, perhaps even spike with an enlarged spread and pull away again.
