Trading Robot Review Most losing trades occurred during: 04:00-08:00 US stock market close + Asian markets not yet open, liquidity is at its lowest 12:00-16:00 Asian afternoon session, the coldest period of the day 21:30-23:00 US stock market open, 1.5 hours after opening, a high concentration of false breakouts Most profitable trades occurred during: 16:00-20:30 European session The robot will be adjusted next month, adding intraday trading time limits I feel that human day traders can also refer to this, especially around the US stock market open, where false breakouts are most frequent.
