To illustrate this problem we can see it on GBP-JPY monthly time frame where stochastic is moving up while MACD is still moving down. At this point we will not know how far the market is following stochastic direction. There are two possibilities which is the middle of weekly time frame or further more to the middle of monthly time frame as shown below. Now that the weekly time frame seem to be broken it is possible that the market might continue moving upside to its upper band or making a sudden reversal. Beware of sudden reversal!!! Because it will have little stopping when it happens. This is very dangerous position to trade because of the unknown situation.
Although we know that eventually the market will go down because of the MACD still moving downwards. But that is only to be confirmed when stochastic is moving inline with the MACD moving downwards again.
