Short Squeeze on Sale of Neuva Esperanza or 1st Gold pour, page-252

Gymjunky,
Don’t leave the 60,000 until end of day. The boys love to sell down to you 1 share in the close, just to push the price down that extra half cent. This means though once a trade is partially filled, that brokerage is payable on the whole order. This is fine if you are comfortable just amending your limit price until the order is filled. However if you wanted to cancel the trade outright and break it into smaller trades, you would still have to pay brokerage on the 60,000 shares, even though only one share had been bought.
Happy to be corrected here and it might be different with other brokers, but that’s what Directshares told me over the phone.
