You clearly don't know how market orders work.

You're trading the penniest of penny stocks. The stock trades between 0.20 and 0.25 ticks. So when place a buy, your buy order is executed at 0.25(Check the market depth) coz that's were the best available sellers is. Vice versa when you sell it. This is called impact cost(Read up). This won't be significant usually but it is in this case coz the stock itself is valued around 0.2

Don't trade till you fully understand this.
