You pick risk. The bot does the scan.
The MT5 trading bot is off until you turn it on. You choose the risk per trade. Venasri calculates the lot from that percent and the symbol, instead of leaving a fixed lot on a Gold chart that is really a 3% bet.
News days are the other half. The bot can pause while high-impact events print, which is the MT5 news filter. You can also run paper mode until the size looks boring enough to trust.
The bot is not the daily loss switch
A bot that keeps trading into a 5% day is how challenges die. Pro at $29.99 a month includes the bot and Equity Guard together. The guard can flatten the book even if the bot is the thing that opened the trades.
Connect the terminal first. The steps are on connect MetaTrader 5. Then open bot control. The free plan lets you link MT5. The bot itself is on Pro.
