The trade entry & exit is fully managed by the EA, which looks for trendlines & support/resistance levels.

An interesting scalper EA that's been in my crosshairs for more than half a year, it finally got its turn , complete with history center data and tick data backtests.

A manual system and EA that only trades during the EU morning that I've had my eye on for a long time. I finally decided to start a forward test for it.
