Start on paper: prove it before you fund it

There is a version of paper trading that lies to you. Frictionless fills, no slippage, and a separate code path that behaves nothing like the live system. You "win" on paper and then get surprised with real money. We built ours the other way. A TradeByBar paper account runs through the same engine and the same risk gate as a funded account. Your contract ceiling applies. Your strategy sizes apply. Copy trading behaves identically. The profit and loss you see in your paper account is calculated with the same logic that drives the PnL calendar, so the numbers you build confidence on are the numbers you would actually be reading live. That makes paper the right first step for everyone, not just beginners. Testing a new strategy? Run it on paper alongside your live account and compare. Tuning your size limits? Watch how the gate clamps your orders before a single dollar is at stake. Curious whether a strategy you want to copy fits your style? Follow it on paper for a week. When you are ready to connect a live broker, nothing about how you operate changes. The dashboard looks the same. The controls are the same. The only difference is the account behind them. Start on paper. Let the results, not the marketing, decide when you fund. Paper results are hypothetical and do not represent real trading. Live trading involves substantial risk of loss, including the risk of losing more than your initial deposit.
