Paper trading is a great idea. I did this for quite some time before deciding day trading wasn't for me.

It sounds like you have developed some trading "rules" - great idea!

Even better if you applied them to your four original buys as this suggests your buy rules were working. Equally you need sell rules - but it doesn't look like you are following them. I see HMH hit 0.95 a week or so ago and this is way below your 10% stop loss. You should be kicked out of that one by now and not still hanging. Today you could have sold at $1.09 so I would have thought a 5% gain off your stop loss bottom may also trigger a sell - that way you are minimisimg your losses rather than stating on an unknown roller coaster.
