Someone said you could vibe code a backtester in 5 hours. Here's what 5 hours, 5 weeks, and 5 months actually get you. I've been building mine for almost 6 years and I'm still not done.

How I kept it honest: no look-ahead, real costs, locked data, tests saved to git before they ran.
Early "wins" like +2,000% a trade were bugs, not edges.
All code + data: https://t.co/lRPpi26u7Q

Shout out to @IamDonWhizzy for asking what my trading tests found 🧵
Thousands of rule versions across memecoins, crypto, stocks & forex, each judged on data it never saw.
Short version: almost nothing beat doing nothing.

Keep the original rule set with the backtest. A good-looking chart means little if you can’t retrace the settings. #AlgorithmicTrading #Backtesting
Same entry, 4 exit rules, 100% real-tick XAUUSD data.
Sabse bada profit: +$967, lekin 9.4% DD par.
Lock kiya: +$386 sirf 1.8% DD par.
Highest profit ≠ best system.

What we do now: write the test down before looking, look once, and post the misses too.
Every card we post goes up before the company reports and gets scored against its SEC filing after. Our first two bars: one hit, one miss.
#backtesting #quant
We tested 13,608 trading rules on NQ. One cleared every discovery gate, then lost to its random control on the confirmation data.
New note on our Substack (link in bio).

Got a 502 unknown_outcome from mt5-gateway?
A 502 unknown_outcome from mt5-gateway means the broker may have accepted the order: check positions before retrying.
Double check before you fire again.

Buy a strategy on qkt Labs and you get the files, not a promise.
The exact strategy file, the exact cost profile and every raw report, each with its SHA-256. Re-run it on the same data with qkt, get the same trades.

Every report behind a qkt Labs listing must match the fingerprint the engine recorded when it wrote it. A report edited afterwards fails the gate.

Ever misplaced a decimal point when sizing a trade?
SIZING 0.5 PCT RISK sizes every trade so that hitting the stop costs half a percent of equity, avoiding decimal errors.
The engine requires a bracket with a stop for it to compile.

A parameter sweep always finds a winner. That's the problem.
Here's how to check whether the winner is real in qkt: sweep, read the warning, then walk it forward onto windows the sweep never saw. Losses stay in.

"95% win rate" stochastic setup.
I tested 272 versions on 11.7 years of S&P futures, costs included.
Profitable in both test periods: 0 of 272.
Win rate isn't the number that matters. Expectancy is.

Every number on qkt Labs comes from a simulation.
The methodology page ends with its own limits section. Here it is, one limit at a time.

$10,000 in my momentum system became $160,725. In the market: $80,973.
Return per unit of risk: 0.50. The market's: 0.51.
So I wrote down 7 upgrades and 1 pass rule before testing any of them. How many survived? #momentum #backtesting
With calude in hand and data in laptop it is very easy to get backtest results like this(see maxDD)..
But trading it and actually making money is altogether a different ball game..

Before comparing test results, find out whether the data and the bar intervals cover the same period. #AlgorithmicTrading #Backtesting
The drawdown ceiling on qkt Labs is 50%, at every account size. Deliberately wide, and every listing shows its drawdown so you can judge that risk yourself.
