Third-party trade copier software is allowed if it follows Blue Guardian's rules and only connects accounts you own. Shared devices are banned, including VPS services linked to multiple traders' accounts, and accounts on shared devices may be flagged for review at payout. VPNs and VPS are allowed, but not to get around the copy, group or signal trading rules. The pages don't mention cloud copiers, so they don't say whether a copier's shared servers count as a shared device. EAs are allowed on every account model if you set them up for your own strategy. Tick scalping (trades closed in under 2 minutes), high-frequency trading and arbitrage bots are banned. The website terms also ban third-party or off-the-shelf strategies marketed to pass challenges. EAs are banned in the monthly competition.
