YV Orbit builds MetaTrader 5 Expert Advisors and the tools to test them properly. Every test we run goes on the record below, including the ones that lost money.

The test record

Numbers are copied from each Strategy Tester or account report. Most tests start from a $1,000 deposit with a fixed 0.01 lot. Select any row to see the original image.

Test	Type	Trades	Win rate	Net	PF	Profit factor bar, line marks 1.00

PF is profit factor: gross profit divided by gross loss. Above 1.00 means the test made money. Backtests show how rules behaved on past data under specific spreads and settings. They do not predict future results. Browse all 15 report images.

Consecutive Candle Reversal

Our first Expert Advisor to pass MQL5 Market validation. It waits for a run of same-direction candles and trades the reversal, with a stop-loss and take-profit on every trade. It is free so traders can test it on their own broker and tell us what they find.

Tools we built for our own work

Most EA problems are found too late, after hours of backtesting. These two tools move the checks earlier and make testing repeatable.

Finds weak spots: missing margin and stop-level checks, unchecked indicator reads, risky loops and state bugs
Checks each indicator against its original source instead of trusting its name
Explains the problem, why it matters and the exact lines affected
Suggests corrected code when you ask for it

Each indicator in the EA gets one of these verdicts

How each EA is built

A result only means something when the rules and test conditions are known. The same four steps apply to every project on the record.

Define

Write down the idea, market, timeframe, entry and exit rules and risk limits before any code.

Build and audit

Code the rules with explicit safeguards, then audit the code and indicators before testing.

Test

Backtest across timeframes and brokers, then forward test on a live chart.

Publish and review

Post the result, good or bad, and decide the next change from the evidence.
