WELCOME TO MARKET MAKERS LAB

Most trading systems are built around one question:

When should I enter?

Mine are built around a harder one:

When should the system refuse?

Market Makers Lab develops systematic trading and execution software for MetaTrader 5.

The research spans volatility compression, opening-range behaviour, intraday price discovery, trend acceptance and rejection.

Different strategies.
One engineering philosophy.

A SIGNAL IS NOT ENOUGH

Before exposure is allowed, the system should know whether the market condition is valid, whether execution is acceptable, whether existing positions are correlated, whether the account can afford additional risk, and whether broker state agrees with internal state.

That means asking:

Did the broker actually create the order?
Is the position genuinely closed?
Does planned exposure remain inside the portfolio risk budget?
Should another correlated trade be refused?
Can the system recover after MT5, a VPS or a connection restarts?

Anyone can program a system to say yes.

The infrastructure is in knowing when to say no.

RESEARCH BEFORE MYTHOLOGY

Market Makers Lab does not claim to know what a specific bank, fund or trading desk is doing.

Large market participants can disagree completely and trade opposite sides of the same market.

What can be studied is the footprint left in price:

- range compression and expansion;
- changes in volatility;
- acceptance outside normal price areas;
- failed breakouts and rejection;
- repeated intraday behaviour around liquidity and time.

The objective is to turn observable behaviour into explicit rules that can be tested, rejected or automated.

Measurable behaviour.
Not institutional fantasy.

PUBLIC IDEAS. MODERN IMPLEMENTATION.

Some Market Makers Lab systems begin with published research.

That is deliberate.

A public hypothesis can be examined, criticised and tested across decades of market data.

The objective is not to reproduce an old strategy unchanged.

Markets evolve.

The objective is to identify what remains testable, remove what no longer survives scrutiny, and surround the resulting signal with modern execution and portfolio-risk infrastructure.

BUILT BACKWARDS

Market Makers Lab starts with execution and risk before adding the signal.

Depending on the system, that architecture can include:

- broker-side protection;
- portfolio exposure limits;
- correlated-risk controls;
- execution validation;
- restart and reconnect recovery;
- account-level safeguards.

A valid signal may still produce no trade.

That is intentional.

The signal identifies an opportunity.
The risk engine decides whether the account can afford to participate.

TEST IT

Use the MetaTrader Strategy Tester.

Use your broker's symbols and trading conditions.
Test different market regimes.
Study the entries.
Study the drawdowns.
And study the situations where the system refuses to trade.

No trading system guarantees future profitability.

Past backtests, simulations or live results do not guarantee future performance.

Market Makers Lab is independently developed and is not affiliated with or endorsed by the researchers whose published work may inspire individual systems.
