TraderPier Review: A Trading Journal That Lets You Replay the Trade

You remember the exit. You were down, you closed the trade, and the chart went your way a few minutes later. What you don't remember quite so clearly is whether there was a good reason to stay in. A screenshot taken after the move isn't much help with that.

TraderPier puts a replay button beside the trade. Open it and you can watch the chart unfold again, instead of judging the decision with the whole day's price action already visible. That connection between the journal and the chart is its strongest reason to be on your shortlist.

This TraderPier review looks at the journal, replay, imports, AI tools and pricing. We explored the public sample journal, replayed a losing trade, checked its controls and ran a short built-in strategy backtest. The examples are demonstrations of the software, not evidence of trading profits you should expect.

What is TraderPier? TraderPier is a browser-based platform for US stocks and ETFs that combines charting, a trading journal, market replay, backtestingBacktestingThe process of running a defined trading strategy against historical price data to evaluate how it would have performed before risking real capital. A well-constructed backtest gives you a statistical baseline — win rate, profit factor, maxRead definition → and paper trading. Paid plans add its Spyglass AI assistant and deeper research tools, with live strategy execution through a supported broker on Quant.

A journal can tell you that you lost money. Replay helps you look at the decisions made along the way.

In TraderPier's sample journal, we opened a short SPY trade with a $62.40 net loss. Its note described a boredom entry without a setup. Expanding the row showed that context; pressing Review opened the chart and a timeline of the entry and exit fills.

The replay has play and pause, single-bar stepping, a position slider and speeds from 1× to 8×. We restarted the sample, moved the slider back to the beginning and advanced it one bar. The chart moved with the playback position. You can also open the trade in the main workspace or choose to redo it in replay.

That makes a practical review routine possible. Stop the chart before an entry and askAskThe ask is the lowest price a seller is currently willing to accept. When you buy with a market order, you pay the ask.Read definition → what justified it. Advance a few bars and ask whether the trade still fits the plan. You are looking at the sequence of events, rather than drawing a perfect entry on a finished chart.

There is still some hindsight to manage. The review panel displays the recorded trade's final net result, and its timeline lists the fills, with future rows dimmed. It is a tool for examining execution, not a completely blind test. For practice without your own recorded outcome sitting alongside the chart, use the separate Market Replay workspace.

Replay and MAE/MFE answer different questions. Replay lets you revisit the chart; MAE and MFE measure how far a trade moved against you and in your favor while it was open. Those excursion tools sit on the paid plans, so don't choose Free expecting both.

The journal is a table first, which is a sensible place to start. Rows show the date, symbol, direction, quantity, average entry and exit, fees and net P&L. There are also columns for excursions and R, with blanks where the information isn't available. Open a row for its notes and setup, or go straight to Review.

Underneath are an equity curve, a P&L calendar and summary statistics. The public sample contained 10 hypothetical trades, with six winners and four losers. Its $347.90 total agreed with the sum of the displayed trade results, and the averages, profit factorProfit FactorProfit factor is the ratio of total gross profit to total gross loss across a set of trades — a profit factor above 1.0 means you're profitable overall, and a ratio of 2.0 means for every $1 lost, you've made $2, giving you a clear, single-Read definition → and expectancyExpectancyExpectancy is the average amount your strategy makes or loses per dollar risked — it's the single best number for evaluating whether your trading approach has a real mathematical edge.Read definition → lined up with those rows at their displayed precision.

One detail made the sample more useful than a tidy green headline: its largest winner contributed $330.25. Remove that one trade and the remaining nine made just $17.65 combined. That isn't a fault in the software. It's the kind of concentration you want a journal to make easy to notice.

The calendar offers month, week and year views. In the journal, trades count on their entry day. The backtest calendar uses a different view of the results, including session P&L with open positions marked at the close. Read those labels before comparing a daily figure with a broker statement.

Playbooks give you a place to keep the rules for a setup and connect journal trades to it. That is more useful than a collection of names such as “breakoutBreakoutA breakout is when price moves decisively beyond a defined level — a resistance zone, a consolidation boundary, a chart pattern boundary, or a prior high — suggesting that the previous supply at that level has been overcome.Read definition →” if each name actually describes what had to happen before you entered. The plan comparison reserves automatic rule-adherence scoring for Quant; having a playbook and having the platform score compliance are separate features.

If journaling is new to you, start with our guide to keeping a trading journal. The replay button is valuable, but it can't supply the reason for an entry you never recorded.

You export a CSV from your broker and bring it into the journal. TraderPier doesn't automatically pull your historical journal trades from a connected brokerage account. That remains true even though another part of the platform offers live strategy execution.

Its supported-brokers guide lists Charles Schwab, Fidelity, Interactive Brokers, moomoo, Robinhood, tastytrade, thinkorswim and Webull. Other CSV formats can use column mapping, with a saved format for the next import. The journal includes CSV export too.

The documented import flow gives you a chance to check the matched columns and preview the result before importing. If you're moving from Tradervue, there is a separate catch: its migration guide says existing tags and notes won't transfer. Keep a copy of those records. Losing the explanation behind a trade can matter more than losing a chart.

The important detail is whether your file includes times. The guide marks some activity exports as dates-only, while others include intraday timestamps. For a dates-only file, you need to add the entry and exit times in the trade's Edit view to place them correctly on the chart. Check the timezone as well: an accurate dollar result is not enough for an accurate replay location.

Think about fills as well as trades. A position bought in two pieces and sold in two pieces produces more rows than one simple entry and exit. Export the actual executions, including quantity and fill price, then compare the resulting position size, average prices, fees and P&L with your statement. Don't assume the limit price in an order record is the price you received.

The import interface says the CSV is read in your browser rather than uploaded as a raw file. Saved journal content is still account data, so that message should not be read as a promise that your entire journal remains only on your computer.

Free is a continuing plan, rather than a short trial. You can try the workspace without an account, then create a free account to keep your work. The signed-out demo has its own smaller allowances; it isn't a complete picture of a registered Free account.

As checked on October 19, 2026, the pricing page showed:

Prices are in USD, before applicable sales tax or VAT. The annual amounts are billed yearly. CSV import/export and trade replay appear on every tier. Trader adds Spyglass, tick/sub-minute charts, excursions and setup analysis; Quant adds deeper analytics, rule scoring and live strategy execution. The advertised AI allowances are about 200 messages monthly on Trader and 500 on Quant. Free requires no card. Subscriptions renew until canceled; cancellation keeps paid access through the billing period, without a prorated refund.

The history window matters more than the storage number if replay is why you're here. You can keep older trades and review their statistics without having chart history available to replay all of them. Selected famous-day demonstrations are also available beyond the normal recent-history window; those examples don't mean an arbitrary old trade is replayable on Free.

For someone reviewing a few recent trades after each session, the free allowance could be enough. If you routinely want to replay every entry and exit from a busy day, you will reach its ceiling quickly. Judge the plan against that routine, rather than the word “free.”

Spyglass is a conversational assistant built into the workspace. Its suggested prompts include marking gaps on a chart, building an indicator, testing a trading rule and turning a weak journal setup into something you can backtest.

That is a different role from simply writing a report about last month's statistics. The proposed workflow is to identify a pattern, describe a specific change, build the rule and test it on historical data. For example, “I keep losing on this setup” becomes a question about which conditions define that setup and whether changing them survives a test.

Specific rules matter. “Only buy a strong breakout” leaves a lot to interpretation. A rule that defines the range, entry trigger, position size, exit and costs is much easier to inspect. AI can help turn an idea into code, but you still need to check that the resulting strategy represents what you meant.

TraderPier's backtesting overview also describes parameter optimization, cross-symbol checks and walk-forward testing. These help you investigate whether a result survives outside the data or settings that made it look good. They don't turn an attractive historical result into a guarantee. Our AI trading-journal guide explains how to turn this kind of output into a useful review question.
