Hi Huaone, your eerie feeling is correct.
TOS Paper will fill you almost immediately on a limit order on the last print; then it fills you almost immediately a tick higher (assuming you’re using an OCO bracket) to exit if things go well.
TOS Reality might fill your limit order about 1 or 2 minutes later while you’ll wait for an average of 1000 or so contracts ahead of you to fill. When you try to get out a tick above your limit order a tick above may also take about 1 or 2 minutes while you’ll wait for a typical average of 1000 or so contracts ahead of you to fill.
In other words: Yes, Scalping ES in ThinkOrSwim's PaperMoney is Unrealistic - at least for one or two quick ticks with limit orders.
Using paper money to scalp for one or two quick ticks with limit orders on 1039 trades over about 10 weeks, I found I was correct 79% of the time for an average gain of 0.267 points after commissions, and the 21% of the time I was wrong average loss was -0.565 points including commissions.
A tick is 0.25 points and this is profitable since 79% * (0.267) + 21% *(-0.565) = +$0.095 per dollar risked.
On $200 risked per trade, total account was $100,000 starting + 200*1039*$0.095 = $119,741 ending balance. Problem is such would rely on getting the unrealistic fills; I did however enjoy the feel for how ES trades.
In TOS Reality only a market order (typically a tick below the print you may want) fills you immediately. I hope you haven’t learned this too late; best in my opinion to learn with very small size and keep track until you know it’s profitable before scaling up.
Also:
-EmotionIsTheBigEvel, above likely means market orders fill immediately
-Abottoml, above might note ES often trades with no mid spread, and I agree TOS staff are incredibly helpful – just ask them.
-Ektrader, above likely also means market orders fill immediately, though I imagine you’re using limits
-Directional, above is spot on and I thought I would add some further details
