Em geral nunca observo o volume independentemente do range da barra, uma subida com volume que nao seja acompanhada de um significativo aumento de range e em geral uma indicacao de que o swing tem alta probabilidade de ser interrompido na barra seguinte.

A isto chama-se "Effort versus Results".
Um texto interessante sobre o tema:
"Frequently, you will see effort with no result. For instance, you may observe a bullish rally in progress
with sudden high volume appearing – news at this time will almost certainly be ‘good’. However, the next
day is down, or has only gone up on a narrow spread, closing in the middle or even the lows. This is an
indication of weakness – the market must be weak because if the high activity (high volume) had been
bullish, why is the market now reluctant to go up? When reading the market, try to see things in context. If
you base your analysis on an effort versus results basis, you will be taking a very sensible and logical
approach that detaches you from outside influences, such as ‘news’ items, which are often unwittingly
inaccurate with regards to the true reasons for a move. Remember, markets move because of the effects of
professional accumulation or distribution. If a market is not supported by professional activity, it will not
go very far. It is true that the news will often act as a catalyst for a move (often short-lived), but always
keep in mind that it is the underlying activity of ‘smart money’ that provides the effort and the result for
any sustained price movement."
