Hey Adam,
It’s very rare for an EA to be consistently profitable for a long period of time. Market conditions change, so we’re always generating new strategies based on the most recent data from the broker/s. An EA may, over an entire 5 year period be profitable overall, but it will, a few times, go through draw downs. We try to avoid these draw downs by regularly analyzing our EAs and selecting the most profitable ones in current market. conditions.
Thanks,
Ilan
