ChartMini Market Replay Tutorial: Historical Chart Practice

Quick Answer

This page is the how-to-use-ChartMini tutorial for market replay. Open the Market Replay hub, choose either Daily Replay or Intraday Replay, start a random historical session, make decisions before future candles appear, and finish by reviewing what you actually did.

ChartMini has two replay environments:

Daily Replay uses daily historical candles across stocks, forex, and crypto.
Intraday Replay uses historical five-minute source data for forex and crypto, with chart periods from five minutes through longer aggregated intervals.

Both environments hide later candles and use random historical starting points. The goal is not to maximize virtual profit. The goal is to create a record of how you read the chart while the outcome was still unknown.

For definitions, use What Is Market Replay?. For a narrow beginner exercise, use Bar Replay Explained. For drill design, use 3 Market Replay Drills. This page only explains the current ChartMini workflow.

Educational use only: ChartMini is a historical chart-practice tool. It is not a broker, exchange, investment adviser, automated strategy tester, or source of guaranteed performance.

Choose the Correct ChartMini Replay Mode

The first decision is not whether to buy or sell. It is choosing the replay environment that matches the skill you want to practice.

Mode	Historical source	Available markets	Best suited to
Daily Replay	Daily candles	Stocks, forex, crypto	Daily-close reading, swing-style structure, slower decisions
Intraday Forex Replay	Five-minute source candles	Forex	Session structure, shorter-term price action, faster decisions
Intraday Crypto Replay	Five-minute source candles	Crypto	Continuous-market price action and intraday decision practice

Open ChartMini Market Replay to choose among these modes.

Use Daily Replay when

your decisions are based mainly on completed daily candles;
you want more time to examine trend structure and major levels;
you want to practice stocks as well as forex or crypto;
you are learning to separate a meaningful daily move from intraday noise.

Use Intraday Replay when

you want to practice decisions at a faster pace;
your process uses forex or crypto charts;
you want to compare five-minute structure with larger chart periods;
you want the Buy, Sell, quantity, Next Bar, and session-review workflow on historical intraday data.

Daily and intraday replay are not interchangeable exercises. Choose one environment for a session and keep the objective narrow.

Before Pressing Start Session

A random chart is useful only when you know what you are trying to observe. Write three items before opening the session:

Practice focus: the one skill being trained.
Decision rule: what must be visible before you act.
Invalidation rule: what observation would make the idea no longer valid.

A compact note might look like this:

Field	Example structure
Practice focus	Pullback decisions in an established trend
Entry condition	Price returns to a marked area and closes back with the trend
No-trade condition	Structure is unclear or price is already extended
Invalidation	Price closes through the level that supported the original idea
Review question	Did I follow the condition before pressing Buy or Sell?

The exact strategy is your choice. The important point is to define it before the next candle reveals the answer.

How to Use Daily Replay

Step 1: Open Daily Replay

From the Market Replay page, select Start Daily Replay. The tool opens the daily replay interface.

Daily Replay supports stocks, forex, and crypto. You select the market category inside the tool, while the specific market and historical segment are randomized.

Step 2: Choose a random-session mode

ChartMini currently provides two random-session modes:

Random segment: loads a historical segment selected by the session logic.
Random time: starts from a randomized historical time within the available data.

Both modes are designed to reduce outcome memory. Neither is a manual symbol-and-date picker.

Step 3: Press Start Session

After choosing the category and session mode, press Start Session. ChartMini loads the historical candles and hides the later part of the chart.

Do not immediately search for a trade. First identify:

the direction or lack of direction;
recent swing highs and lows;
areas where price previously reacted;
whether the current candle is near, through, or far from those areas;
whether your written setup is actually present.

A valid replay decision can be wait. A session does not need a trade to be useful.

Step 4: Use Buy, Sell, quantity, or Next Bar

The controls let you record a simulated long or short decision with a chosen quantity. Pressing Buy or Sell creates a simulated trade inside the session; it does not send an order outside ChartMini.

Use Next Bar when no action is required or after recording a decision. In Daily Replay, it reveals the next daily candle.

Before each advance, record a short reason:

trend continuation condition present;
level held but confirmation absent;
setup invalidated;
no trade because structure is mixed;
position maintained because the original condition remains valid.

This prevents the review from becoming an explanation invented after the chart is complete.

Step 5: Finish the session

Press Finish when the practice objective has been completed or the available segment has reached a natural review point. Finishing opens the session summary rather than immediately erasing the result.

Use that summary to compare your actions with the rule you wrote before the session.

How to Use Intraday Replay

Step 1: Choose Forex or Crypto

Open either:

These landing pages open the intraday simulator with the relevant market preselected.

The current intraday release uses historical five-minute source data. The forex and crypto pools are separate, and each new session chooses a supported market and historical starting point at random.

Step 2: Select Random Segment or Random Time

The intraday interface also offers Random segment and Random time modes. Choose the mode before starting.

Randomization means:

you cannot rely on a famous historical event you already remember;
you may receive a market you would not normally choose;
your first task is reading the visible structure rather than searching for a preferred symbol;
the session is better suited to blind price-action practice than exact event reconstruction.

Use a dedicated event or session guide when a known date, timezone, or economic release is essential to the exercise.

Step 3: Select the chart period you want to read

The underlying data is five-minute candles, but the TradingView chart can display broader periods. This lets you compare the same hidden historical path at different levels of compression.

A practical sequence is:

inspect a broader period for structure;
return to the operating period for the decision;
keep the selected period stable while the setup develops;
avoid changing periods only to search for a chart that supports the decision already made.

Step 4: Understand how Next Bar advances

In Intraday Replay, Next Bar follows the period currently shown on the chart.

For example:

on a five-minute chart, it advances one five-minute candle;
on a fifteen-minute chart, it advances enough five-minute source candles to complete the next fifteen-minute bar;
on an hourly chart, it advances to the next complete hourly bar.

This avoids presenting a partially formed aggregated candle as though it were complete.

Step 5: Record simulated decisions

Use Buy, Sell, quantity, and Next Bar to create the practice record. The controls update simulated positions and P&L against the replayed chart.

They do not model all live-market mechanics. A displayed historical bar cannot prove that a real order would have filled at the exact displayed price, especially when spread, queue position, liquidity, slippage, latency, and intrabar sequencing matter.

Step 6: Finish and review

Press Finish to open the summary. Review the trade count, simulated P&L, and recorded trades. An optional AI-analysis flow is available after authentication, but the most important evidence is still the sequence of actions you recorded before the outcome was visible.

What the Main Controls Mean

Control	What it does	What it does not prove
Start Session	Loads a random historical session in the selected mode	That the chosen market or date matches a live-trading plan
Buy	Records a simulated long-side action and advances when applicable	That a live buy order would receive the same fill
Sell	Records a simulated short-side or sell action and advances when applicable	That borrowing, margin, or exchange shorting would be available
Quantity	Changes the simulated position amount used by the session controls	That the size is suitable for a real account
Next Bar	Reveals the next complete chart period	Every tick or event inside that candle
Finish	Ends the practice run and opens the summary	That the session result predicts future performance

Treat each control as a way to document a decision, not as a broker-order emulator.

A Complete ChartMini Session Runbook

Use this sequence when you want a repeatable session rather than unstructured chart browsing.

1. State one objective

Examples include:

wait for a pullback instead of chasing;
classify trend, range, or transition before acting;
avoid entering directly into a prior reaction area;
record every valid no-trade decision;
keep the same invalidation rule throughout the session.

2. Select Daily or Intraday Replay

Choose based on the decision horizon, not because one chart appears easier.

3. Select the market category

Daily Replay supports stocks, forex, and crypto. Intraday Replay currently supports forex and crypto.

4. Choose the randomization mode

Use Random Segment or Random Time. Do not restart repeatedly until a preferred chart appears; that introduces selection bias into the exercise.

5. Read the initial context

Before pressing Buy, Sell, or Next Bar, write:

current structure;
nearest relevant level;
what would qualify as a setup;
what would make you wait;
what would invalidate the idea.

6. Decide before advancing

Every step should produce one of four records:

Buy;
Sell;
hold an existing simulated position;
no trade.

“No trade” should be a deliberate decision, not an empty gap in the journal.

7. Finish at a logical review point

Do not continue merely to turn a losing simulated result into a positive one. End when the selected exercise is complete.

8. Review process before outcome

Use this order:

Was the initial market classification reasonable using only visible data?
Did each action meet the written condition?
Did any rule change after a loss or missed move?
Were no-trade decisions recorded consistently?
Did the selected chart period match the exercise?
What single process adjustment belongs in the next session?
Only then review simulated P&L.

What to Record Outside the Tool

A lightweight external log makes sessions comparable over time.

Field	What to record
Session date	When the practice was performed
Replay mode	Daily, intraday forex, or intraday crypto
Randomization mode	Random segment or random time
Display period	The chart period used for decisions
Practice focus	One skill or rule
Initial structure	Trend, range, transition, or unclear
Decision sequence	Buy, Sell, hold, and no-trade actions
Rule exceptions	Any action that did not match the written rule
Review result	One thing to keep and one thing to change

What ChartMini Does Not Simulate

ChartMini replays closed historical candles. It does not reproduce:

live exchange or broker connectivity;
real order routing;
bid/ask queue position;
Level 2 or full order-book depth;
every spread, fee, commission, financing charge, or borrow rule;
real slippage and latency;
every tick inside a candle;
guaranteed stop or limit fills;
market impact from your hypothetical order;
the emotional and financial consequences of risking real money.

This boundary matters. Research comparing historical market replay with interactive multi-agent simulation notes that a replayed market generally does not react to the experimental strategy as a live market may. Replay is therefore useful for chart-reading and decision-process practice, but limited for evaluating market impact or exact execution quality.

Use a broker demo when the objective is platform-specific order entry. Use automated backtesting when the objective is testing coded rules across a dataset. The Market Replay vs Backtesting vs Paper Trading guide provides the method boundary.

Common ChartMini Tutorial Mistakes

Restarting until a preferred chart appears

Randomization is part of the exercise. Repeated restarts select for familiar or attractive setups and weaken the blind-practice value.

Treating every session as a profit contest

A positive simulated result can come from a poor decision. A negative result can follow a correctly executed rule. Grade the process first.

Changing chart periods to justify an entry

Multi-period review can add context, but repeatedly changing the period after deciding can become confirmation seeking. Define how periods will be used before the session.

Assuming Next Bar reveals every intrabar event

A completed candle shows open, high, low, and close. It does not establish the exact sequence of every transaction inside that interval.

Ignoring no-trade decisions

Waiting is part of execution. Record why a setup was absent rather than pressing Buy or Sell merely to create activity.

Treating simulated fills as broker evidence

ChartMini is not intended to validate live order quality. Spread, liquidity, latency, and market impact require a different environment.

Frequently Asked Questions

How do I start a ChartMini market replay session?

Open the ChartMini Market Replay page, choose Daily Replay or an intraday Forex or Crypto session, select a random-session mode, and press Start Session. ChartMini then loads a random historical market and keeps later candles hidden.

Should I use Daily Replay or Intraday Replay?

Use Daily Replay for daily-candle and swing-style chart reading across stocks, forex, and crypto. Use Intraday Replay for faster Forex or Crypto practice based on historical five-minute candles, with broader chart periods calculated from that source data.

Can I select an exact symbol and historical date in ChartMini?

Not in the normal practice flow. ChartMini selects a supported market and historical starting point at random. This is intentional because randomization reduces the chance that you remember the outcome before making a decision.

What does Next Bar do in ChartMini?

In Daily Replay, Next Bar reveals the next daily candle. In Intraday Replay, it advances one complete period at the interval currently shown on the chart. For example, a fifteen-minute chart advances enough underlying five-minute candles to complete the next fifteen-minute bar.

Are ChartMini Buy and Sell actions real trades?

No. Buy and Sell create simulated positions inside the replay session. ChartMini does not connect to a broker, exchange, wallet, or live account, and it does not send real orders.

What can I review after finishing a ChartMini session?

The session summary shows the simulated result, trade count, and the trades recorded during the session. Optional AI analysis is available through the account-gated analysis flow, but the basic summary should still be treated as a practice record rather than proof of future performance.
