Inflexion
When there is a mismatch between net speculative OI (longs-shorts) and net number of speculators (long traders-short traders) we have inflexion and it can be a useful trading signal.
To interpret the inflexion we need to consider the market context as it is unclear how price may behave when inflexion happens. We might have reversal or continuation.
When there is inflexion it is highly likely that we might have potential shift in speculative positioning and it is a good indicator to identify change in sentiment.
