Ill try to explain and hopefully you get to read this. One could fraudulently use non-existent trades to hide a short position in the stock of Exph or any stock. some could have access to the same access an introducing broker may have to the clearing broker’s system and falsely place Exph buy orders, which would cancel the next day by maybe claiming the orders were placed in error. one or some could enter and cancel these fictitious buys almost daily concealing the size of the short position from the clearing broker, and avoiding serious financial consequences. All in my honest opinion.
