TL;DR

  • Pick ThinkorSwim paperMoney if you want the most realistic execution simulator on the market, with full options chains, futures, complex orders, and the same platform real ToS users trade on. Free with a Schwab account.
  • Pick ChartDojo if you can already place a trade and want feedback on the decision behind it: was the entry good, was the stop logical, was the sizing right, was the reasoning sound. Free trial.
  • These are not the same product. ToS paperMoney simulates filling orders. ChartDojo grades the thinking that leads to orders. Many serious learners use both.
  • If you only pick one as a beginner, ToS is more capable but steeper. Webull paper trading is gentler. ChartDojo is the missing layer between paper trading and live trading where decision quality gets honest feedback.

What ThinkorSwim paperMoney is

ThinkorSwim paperMoney is Charles Schwab's paper trading mode inside the ThinkorSwim desktop and mobile platform. It mirrors the real ToS environment: same charts, same scanners, same order routing, same options chain, same futures execution. You get a $100,000 virtual cash account and a $100,000 virtual margin account refreshed on request, and orders fill against live market data with realistic latency and slippage modeling.

For experienced traders who want to test a strategy without risking capital, paperMoney is the most realistic free option available outside of a prop firm simulator. The cost of admission is the ToS platform itself, which is powerful but has a learning curve that beginners often find intimidating.

What ChartDojo is

ChartDojo is a different category. You are not simulating trades you would execute on a broker. You are presented with real chart setups and asked to make a decision: where would you enter, where would your stop sit, what is your target, what is the reasoning. AI then grades the decision against trader best-practices and shows you where the thinking holds up and where it does not.

The closest analog is paper trading, but the focus is on decision quality rather than execution outcome. A trade can win because the market moved randomly in your favor while your reasoning was flawed. ChartDojo flags that. A trade can lose because the market moved against a well-constructed thesis. ChartDojo flags that too. Outcome and decision quality are separable, and most paper trading tools only show you the outcome.

Feature comparison

Asset coverage

  • ToS paperMoney: US stocks, options, futures, forex. Full Schwab broker coverage.
  • ChartDojo: Chart-based analysis, broker-agnostic. Focused on the setup and decision, not on simulating broker fills.

Realism of trade execution

  • ToS paperMoney: High. Fills against live order books with realistic latency. Closest free tool to live execution.
  • ChartDojo: Not a focus. ChartDojo is not trying to simulate broker mechanics. It is trying to grade the decision before any broker is involved.

Feedback on decision quality

  • ToS paperMoney: None. You see P/L. The platform does not tell you whether the entry was good, whether the stop was logical, or whether your reasoning aligned with the setup.
  • ChartDojo: Core feature. AI grades entry, stop, sizing, and reasoning against trader best-practices and shows you what a paid coach would flag.

Learning curve

  • ToS paperMoney: Steep. The platform is professional-grade and dense with features. Many beginners bounce off it for the first 30 days.
  • ChartDojo: Low. You look at a chart, mark up your decision, get scored. The product is built around the practice loop, not the platform.

Pricing

  • ToS paperMoney: Free with a Schwab account.
  • ChartDojo: Free trial, with paid tiers for more practice and deeper feedback.

Where ThinkorSwim paperMoney wins

Realism. If your goal is to rehearse the mechanics of placing orders, managing options legs, or routing futures, paperMoney is the realism standard. The execution simulation is good enough that experienced traders use it to test strategies they will run on live capital the next day.

Asset breadth. Options chains, futures with proper tick sizing, complex multi-leg strategies, forex pairs. If your strategy needs those, ChartDojo is not a substitute.

Platform continuity. Practicing on the same platform you will trade live on is a real edge. Hotkeys, layouts, watchlists carry over. ChartDojo does not solve this.

Maturity. ToS has been refined over a decade. The simulator handles edge cases (after-hours, halts, options assignment) the way a real Schwab account would.

Where ChartDojo wins

Decision feedback. ToS shows you what happened. ChartDojo shows you whether the decision was good. The two answer different questions. If your paper trades are losing money and you do not know why, ToS will not help you. ChartDojo is built for exactly that gap.

Speed of the practice loop. A full paper trading session on ToS can take hours: open the platform, build the setup, wait for fills, manage the position, journal afterward. A ChartDojo practice loop takes minutes per setup: look, decide, get graded, move on.

Beginner accessibility. ToS asks beginners to learn the platform before they can practice. ChartDojo lets a beginner start the practice loop on day one without needing to know what a bracket order is.

Coach-equivalent feedback at no human cost. Paid trading coaches charge $100 to $300 per hour to do roughly what ChartDojo's AI does: look at your decision, tell you what a more experienced trader would have done differently. ChartDojo replaces a chunk of that for the price of a free trial.

Who should choose what

Choose ThinkorSwim paperMoney if: you trade or plan to trade options, futures, or complex multi-leg strategies; you already have or plan to open a Schwab account; you want execution simulation as close to live as possible; you have the patience to learn a professional platform.

Choose ChartDojo if: you are beginner-to-intermediate, you want graded feedback on your trade decisions rather than execution practice, you are tired of paper-trading without learning anything, or you cannot afford a $200-an-hour mentor but want similar feedback on your thinking.

Use both if: you are serious about learning. ToS paperMoney handles execution rehearsal. ChartDojo handles decision rehearsal. These are complementary, not competing.

Honest caveats

ToS paperMoney does not magically prevent the most common beginner mistake of trading too much. Volume of paper trades on a realistic platform does not equal learning. Without a journal or external feedback loop, beginners can run 500 paper trades and only learn that they like the feeling of clicking buttons.

ChartDojo does not replace the experience of managing a live position. Once real capital is at stake, the psychology shifts. Both tools handle preparation. Neither handles the moment when your stop is being tested and your hand is on the close button.

FAQ

Is ThinkorSwim paperMoney really free?
Yes, with a Schwab brokerage account. No funding required to use paperMoney specifically.

Does ChartDojo work for options or futures?
ChartDojo's focus is chart-based decision practice. For options chain analysis or multi-leg strategy testing, ToS paperMoney is the right tool. ChartDojo and ToS solve different problems.

If I only have time for one, which should I use?
If you are a complete beginner, start with Webull paper trading (gentler) or ChartDojo (decision-first). Move to ToS paperMoney once you understand the basics and want a more realistic execution environment.

Can ChartDojo replace a paid mentor?
For decision-quality feedback, it can replace a significant portion of what a paid coach does. For accountability, community, and live-market psychology coaching, a human mentor still has unique value.

Verdict

Use the right tool for the right job. ToS paperMoney is the realism standard for execution simulation. ChartDojo is built for the decision-quality layer that paper trading platforms ignore. Treating them as competitors misses the point. The right question is whether your weak link is order execution or decision making, then pick accordingly.

For most beginners we see, the weak link is the decision. Hours of paper trading without feedback teaches you to click buttons, not to read setups. That is the gap ChartDojo was built for.
