One-on-one coaching for systematic traders, from first system to full portfolio. The shape on this page is my own real-money account, drawdown included.
Most traders don’t fail for lack of ideas. They fail in three predictable places.
Too many rules, tuned settings, costs left out. It looks perfect on paper and falls apart in the first months live.
“Wall Street bubbles, always the same.” Udo Keppler, Puck, 1901.
Every system has long, painful stretches. Without other systems to offset it, each drawdown feels like proof it’s broken.

The override after a bad week, the system dropped at the bottom of its drawdown. The system was fine; the decision wasn’t.

You work on your own platform with your own data, so you understand and own every rule. My job is to question the logic, and the assumptions you didn’t know you were making.
Turn the idea into exact rules, and decide what success looks like before you test anything. The first question for any system: when should it make money, and when should it lose?
Example
Review your backtest, then stress it across periods, settings and costs. If the edge only lives at one lucky value, it isn’t an edge.
Example: does it survive when every setting moves?
Shorter lookbackLonger
Systems that work together, not just side by side. Trend following, mean reversion and hedges each have their season; a portfolio lets one carry the others through theirs.

Position sizing and risk rules for your account and the drawdown you can actually sit through. You choose your risks, not your returns.
Example
| Account | €100.000 |
|---|---|
| Risk per trade | 0.5% |
| At risk if stopped | €500 |
| Stop distance | €4,20 |
| Position | 119 shares |
Clear criteria for going live, for stepping in, and for leaving it alone. Then the hardest part: staying with it long enough for it to work.

Most traders switch the system off somewhere in here. The rules didn’t change. Drawdowns are part of the design, not a reason to redesign.
One emotional decision that costs 2% of this account is €5.000: five months of Partner. That is what Partner is for.
One idea, taken from concept to a tested, tradeable system.
Three weekly sessions: specify, test, size and decide. You leave with one backtested and stress-tested system, sizing and risk rules for your account, clear criteria for going live and for stopping, and a process you can repeat.

I’m Koen van Goch. My first trades, in 2022, had no strategy, no stops and no plan. The Turtle Traders taught me to follow rules instead of predictions. Today I run 47 systematic strategies live on US equities.
If you say you want low drawdowns and your system says otherwise, I’ll ask you why. Expect a direct opinion, not a pat on the back. Mentored by Laurens Bensdorp, Alexei Rudometkin, Yvan Byeajee and Thami Kabbaj.
No. You place your own trades on your own account. I never tell you what to buy, sell or hold, or when. Every decision stays yours.
No. You build on your own platform with your own data, so you understand and own every rule. If you can’t code yet, you need to be willing to learn.
One-on-one on Zoom, in English or Dutch, one session a week so you have time to do the work in between. Each session starts by reviewing what you built.
Because I’d rather you see an ugly drawdown before you meet one with real money. The figures come straight from Interactive Brokers, time-weighted and net of fees.
Yes. Extra sessions are €247 per hour, during or after a programme.
Traders who finished Core and trade their systems live, ideally with a portfolio from around €150.000, who want their decisions challenged rather than approved.
No. Consiquant provides education and system-building support. Trading involves risk, and past results are no guarantee of future results.
Thirty minutes on where your trading is now and where you want it to go. You’ll know which programme fits, if any.
