Having statred using the divergence as a confirmation to the RSI signal only a month ago or so I have never seen this scenario.
The RSI is showing a small + divergence and that may be because the readings are so low that there isn't any more room for the RSI to go down along with the price. But the Stoch isn't budging from its low reading. I am glad I decided to wait for a +div in the stoch before going long again. Although in the past I thought that a divergence in the RSI is all that I need to see to follow the RSI signal I am now seeing that the Stoch divergence is an important confirmation to which I have to pay attention.
