Both RSI and Stochasitcs at the 15m interval tested the divergence trendline which held, followed by declining prices and trade volume. Crossover occurred but didn't have any bearish candle to confirm the divergence at that point.
Divergence on RSI at 30m to 2h intervals is also more apparent which to me implies that it will be a while before a reversal sign is seen, if at all. I'd estimate that if one isn't seen within the next 4-6 hours that it was a false signal.
