Systematic index trader and developer. I build mechanical trading systems and test them the hard way: 16 years of history, two independent data feeds, out-of-sample epochs, measured spreads and commissions — and every idea that fails the test goes to the archive, not to the product. - Versione: 1.1

Quartz DAX is a fully mechanical Expert Advisor built and tested for the DAX (DE40 / GER40) cash session. It takes at most one trade per day, sets a stop-loss before every entry, sizes the position from that stop and closes at the end of the session - every day, without exception. No martingale, no grid, no averaging, no hidden trades. Two account profiles are built in: Personal and Prop-firm.
Key Features
Stop-loss on every trade. The stop is placed at entry, before the trade exists. The position size is calculated from that stop as a fixed percent of equity, so the risk of every trade is known in advance.
One trade per day at most. The EA waits for the session to choose a direction and takes one trade in that direction. No prediction, no news trading, no re-entries.
Always flat at session close. Nothing is held overnight: no gaps, no swaps, no weekend exposure.
Account profile in the first input. Personal: 1.0% risk per trade, no loss guards. Prop-firm: 0.5% risk per trade, daily loss stop 4%, total loss stop 8% from the EA-start balance - built to stay inside typical 5% / 10% challenge limits. Custom: set the risk and the guards yourself. No set files needed.
Loss guards that only close. When a guard triggers, the EA closes the position and stops trading. It never widens a stop, never adds to a trade, never averages down.
Built-in day filter. Skips days whose conditions historically carry less follow-through. Every skipped day is reported in the journal with its reason.
Spread guard and margin check. No entry while the spread is abnormal; the lot is reduced to what the free margin can carry, so the server never rejects an order.
Position sizing cross-checked against the contract size, so a wrong tick-value in a broker's symbol specification cannot inflate the lot.
Minimum-lot fallback for small deposits, with a loud warning that shows the real risk of the trade.
On-chart panel. Session state, active profile, filter state and position state at a glance.
Optional trade journal (CSV) and optional Telegram notifications - both OFF by default.
Every input is open and documented. What you see in the inputs is what the EA does.
How do I start
1. Attach Quartz DAX to a DE40 / GER40 chart, H1 timeframe.
2. Set the session to your broker's server time. Defaults are 10:00-18:30 for EET / EEST servers (most EU brokers). If your server time differs, shift SessFrom / SessTo accordingly.
3. Choose the Account profile: Personal or Prop-firm. Leave the rest at defaults.
4. Enable Algo Trading. The panel shows "session active" once the session has started.

Backtest
Strategy Tester, DE40, 2019.01 - 2026.08, real tick-data spreads, deposit 100 000 USD, default settings. Personal profile: +380% with a maximal relative equity drawdown of 23.0% (600 trades, profit factor 1.55). Prop-firm profile: +126% with a 12.1% drawdown, loss guards never triggered. These are Strategy Tester results, not a forecast. The win rate is below 50% by design (37% of trades are winners): the average winner is about 2.6 times larger than the average loser. If you compare with a "90% win rate" EA, compare the drawdown first.
Frequently Asked Questions
1. Does it use a grid or martingale? No. One position, one stop, closed at session end.
2. Can I use it for a prop-firm challenge? It was built for that. Choose the Prop-firm profile: 0.5% risk, daily 4% and total 8% loss guards. Check your firm's rules on EAs and on news trading yourself - the EA does not trade news, but firms differ.
3. Why is the win rate below 50%? Because the average winner is much larger than the average loser. A high win rate with a small average win is the signature of grid systems - this EA is the opposite.
4. What if my broker's server time is not EET? Set SessFrom / SessTo to the DAX cash session in your server time (09:00-17:30 CET). The panel and the journal show the session state so you can verify.
5. Does it hold trades overnight or over the weekend? Never.
6. How many trades will I see? Up to one per day; some days are skipped by the day filter or by the spread guard. Zero-trade weeks happen and are reported in the journal.
7. What deposit do I need? From about 1 000 USD the position size follows the risk setting exactly; on smaller deposits the minimum-lot fallback trades the broker minimum and warns you about the real risk.
8. Can I run it on US500 or US30? The inputs allow it, but the EA was tested and tuned on the DAX only. Backtest first.
9. What happens after a loss guard triggers? The EA closes the position and stops. Total-loss stop: review the account and re-attach with ResetProtectionBase=true to resume. Daily-loss stop: trading resumes the next day.
10. Is there a live account monitoring? A public signal will be linked here when it reaches the platform's minimum history.
