I literally got a call after my 13th order was rejected from a lady that advised me I could only put in an order for the last sale price 0.049. After a very big argument with her and her continuing to tell me all orders over the last sale price we would be rejected I hung up the phone and placed an even bigger order to cover onto 0.055 and after rejecting this order they temporarily suspended my account from being able to place buy orders. She kept saying that they had to maintain an orderly market and the increase from 0.049 to 0.054 was too great. But then even just picking up the shares on offer for 0.051 was rejected. Surely this can’t be allowed. She said if I put an order in for last sale price I might get shares even cheaper... which in the flip side means if I wanted to sell some shares I’d have to sell them for less in order for them to allow the transaction. I find that quite concerning and manipulative.
