Hello Pedro and Maria.
I had to give up for now with BlackBull, because their swap fees are crazy high on the institutional trading account. I had the Enigma FX EA running on the 4h timeframe, but even though I won on the trading, I ended up loosing overall, because the swap fee was so high. Never happens on my accounts with other brokers. An EA which is fast in fast out like the Dark Mimas may work well with them.
Best
