I lost a significant amount because 東方証券株式会社 (The name of the company (English translation) is “Toho Securities Company”.) did not execute my stop loss during a flash crash. They said the market was illiquid. Other brokers managed to execute. I have no proof they did not trade against me. Avoid.
Pros: Great customer service|Copy trading available
Cons: Some tools only available on higher tiers|Slow to add new assets
