Sure, you can use Expert Advisor but you have to make sure that the trades it opens are not the same as those of other traders, because this violates our terms and conditions by being Copy Trading.
Example:
Marco browsing social media finds a group of traders promising to get capital from Prop Firms by passing evaluation steps with a bot.
Marco buys a bot/expert advisor from this group of traders and places it on his trading account
Marco passes both challenge stages and the account is passed through the checks to become a Funded Trader.
During the checks it is discovered that the bot they sold to Marco opened the same trades to all the people who bought it.
This is Copy Trading, and it is strictly forbidden in Prop Number One, your account will be closed and you will not be entitled to a refund.
At Prop Number One we reward genuine Traders and reject all traders who see Prop Firm as a way to get rich quick using “Tricks” or various Escamotages.
