I'm sure the point will come where I use increased sizing. But that's nothing I want to try until my confidence increases according to my experience doing this. But the problem is that increased sizing over 200 shares also affects how the trades go through with market orders, because these are big cap tech stocks, the fill might be spread along with the spread.. which will mean more expertise and an adjustment in how my scalping evolves.
Would the effect of variable position sizing show accurately enough on your sim platform to get a quick and dirty feel for the result? What if you round to 100 lots?
Well for one thing, I prefer the big cap stocks where there is the tempo of the market to deal with that I can relate to more easily and it is safer. Plus I don't trade without having those indexes just above the chart and that is what I keep my eye on mostly, because it will show me the way these heavy weighted stocks are going to do ahead of time. That is the secret sauce of what I'm doing. The Medved Trader way of displaying these indexes really is very clever the way it makes seeing the market moves so much easier in these index moves.
The simulator is the exact same thing as the Think or Swim platform, you just press a button when you launch it if you want the Simulator side or the Real money side. I don't know but it seems to have everything.. seems to be very much focused on futures, etc. I'm just using the active trader bit of it to buy and sell and use Medved for everything else. Which probably also accommodates what you describe. But I'm not focusing on any of that right now. Enough to deal with now without complicating things.
When I've pressed the wrong button and have ended up with 200 shares, inadvertently sizing up.. instead of selling. Or any other dumb thing I've convoluted along the way, the position & sizing is always showing up on the panel. Then I hit.. "Flatten Now".. LOL
Yes. What is happening behind the algorithms I don't want to know. What I see is that if the right edge of the index panel is increasing, decreasing, level, slowly pointing up etc.. the 1 minute candles coming up will reflect that most of the time, so much so that you know ahead when a candle will go red or green or churn, etc. It took a while for me to see this detail to the point I can say yes.. it does, almost 90% of the time. The VIX index panel is also important to watch for stronger confirmation.
I'm in Australia and don't trade US mkt, I had assumed indexes and major stocks may have moved in tandem or close enough to make it difficult to beat.
