Not to come off too harsh, but I am not sure what you are trying to do or what your strategy exactly is? B/C from what I am reading, you are not day trading at all but merely trying to capture .01 price movements in a $90 stock. If this is your strategy, then you are doomed to fail, because this is not a strategy at all, it is just gambling as another poster put it. Except you are gambling with horrible odds once you count in the bid ask spread and tendencies to accept winners that are smaller than losers.
The reason I know it's a losing strategy is b/c I had the same mentality when I first started day trading. I thought all day trading included was buying stocks and then selling them at a higher prices so I tried scalping for small penny price movements, and if they worked I just figured I could scale up bigger to make more money. This is not how trading works though, you need to buy or sell something for a reason. And a proper reason isn't "well i think in the next minute the price will go up or down a few cents", it needs to be a reason like "I think the price will go up or down in the next half hour or more because of X". The main key is the variable X, you need a reason for price movement other than random noise.
My advice is similar to many of the other posters, you need to think longer term and start out small. Identify a larger trend and go from there. On top of that, stop trading the same stock everyday, there is going to be no rhyme or reason to the price movement of GS on a one minute chart on a day where there is no news affecting its movement. Find stocks or ETFs where that company or sector has market driving news for the day and trade those. Also take smaller positions so you can let trades ride out longer. For example, you have been frustrated over taking $100 losses when GS moves against you a few cents, well guess what that will happen to a stock that trades over 10 mil shares a day with a price in the $90 range. Where as if you bought say $10k worth of QQQ, you could actually set up a proper stop in place that would actually signal a failed trade while limiting your losses to the levels you were used to getting after a few cents and you would be forced to let your trades run in order to get some good profit.
Having said all of that, the big elephant in the room is the notion that you cannot afford to lose any money on a trade. If this is true then I hate to say it but you should stop and get your life/finances in order until you are in a position to be able to trade without fear. Any successful trader will tell you that you will most likely lose money in the beginning and that the learning curve is harsh earlier on. I made the same mistake when I was younger, I quit my job and tried to make it as a full time trader without actually knowing what i was getting myself into. It is hard enough to become a profitable trader alone, without having the burdon of being profitable and being profitable enough to support yourself 100% via trading. It makes every loss seem twice as bad b/c you are losing money you have and putting yourself more in a hole when you need to cover rent.
