April OE week, very perplexed

Well it turned out to be an awful expiration week for me. My execution was downright pathetic. I had some great ideas I absolutely ruined, that should have been big plays for me. I was truly my own worst enemy. I spot on called the moves in OIH, DIA, and RIMM and got in return losses. I tryed to buy a grand worth of OIH puts at 1.05, for some reason my brokerage said I had no buying power? that threw me off and didnt play it. 2 days go by and it hits a high of 5. I am still confused about that one. Later I bought 10 contracts at RIMM at .65. It gapped down the next day, and the contracts are going for .20, I buy 20. I am on lunch from work and am in a hurry. I decide to buy more. Put an order in for 30. Im following it as the contracts move in my favor and are going for .45. I decide to sell since Im working and cant follow as close as I would like. For some reason I cant sell. I am frustrated and dont know whats going on. I am talking to customer support, and being rude to them wondering what the hell is going on. Turns out I actually put a sell order in for 30 at .20 and sold all of my contracts, thinking I bought 30 more for 60 total. Whenever I clicked on the order ticket, I didnt truly know how to get a buy ticket to come up, so a sell ticket always came up and I would have to manually change it from sell to buy. Well I filled my order but never changed the "CRUCIAL AND MOST IMPORTANT PART OF THE ORDER" sell to a buy. I didn't even review my order, I just wanted to get it in fast and clicked submit. $1500 mistake for being completly ignorant, showing a total lack of disipline, and a true display of laziness. Then I take it out on the nice broker who is just trying to help me. And on top of all this, I am trying to live life in with an equanimous mind set. I think I better go meditate. I sent out a lot of bad karma this week. So god/universe/consciousness gives me a gift in the courts dismissing my jay walking/public intox charges, and I selfishly go out and spread bad karma for not being prepared. Lets look at some charts.
