It looks like there was an issue with a widespread at the time the position was modified, this can happen not long after the markets have opened and also if a trade has just opened when there is low liquidity, the error message states that the new TP must be <= the asking price, the values were:
ASK: 1.07783
TP: 1.08365
When the spread widens the bid and ask price gap widens, I have made a note to suppress the attempted modification if this event should happen again for the next update to be published.
