Tried adding Bloodhound signals as profit targets in Blackbird, does not work apparently? I've also tried the price vs. indicator value comparison for the same, w/o getting it to work. I'm using pivot levels to define the signals/exits. I've tested both RTH/ETH setting to exclude any custom session template issues. Also the intraday close/settlement price setting is used to generate the pivot levels.
Also, it appears that saving a custom rule will not always stick. The issue occurs when changing a generic setting (for example a PT 10 ticks to a custom rule). After reloading the historical data, the settings will jump back to the generic setting (although the custom rule was saved).
