ARTY Price Chart – April 22, 2026

Signal Recap

Our original signal on ARTY carried an edge of 25.46%, suggesting a strong statistical probability of outperformance. We entered at $50.89 with a clear exit framework: close positions that fail to achieve 3% gain within 10 days, maintain a hard stop-loss at -10%, and track performance across multiple time horizons.

Historical Comparison

Our current position has reached the 15-20% performance range after 10 days. Looking back at the signal table reveals something important: this range had only one historical precedent, and that historical case produced exactly the same 10-day return of 16.27%.

However, the original signal called for a Close action at this range. Why? Because the historical data showed zero gain at the 20-day, 30-day, and 60-day marks for this particular range. One data point is not enough to establish a pattern. I must respect what the signal algorithm is telling me.

Yet this creates genuine tension in execution. A 16% gain after 10 days is objectively strong. We far exceeded the 3% threshold required to hold. Our position is safe from the exit rule that targets underperformers. Still, the absence of 20d+ continuation in that single historical case suggests mean reversion risk or profit-taking pressure ahead.

Exit Decision

HOLD – Monitor for exit signal

Despite the historical signal recommending a close at this range, we hold because: (1) performance is strong and well above the 3% retention threshold; (2) the hard stop-loss at -10% remains intact; and (3) we have an opportunity to capture mean-reversion patterns over 20-60 days if the broader market supports continuation.

Next Targets & Exit Plan:
– If price reaches $61-62 range (20d historical proximity), consider partial profit taking.
– Monitor for a close below $54.80 (current price minus 7% trailing stop) to trigger exit without waiting for full stoploss.
– If holding through day 20, assess whether the position has fallen back below the 10-15% range; if yes, close on that mean reversion signal.
– Hard exit at $45.80 (-10% stoploss from entry).

Lessons and Key Takeaways

Historical data serves as guardrails, not chains. The signal algorithm recommended closing at this range, but one historical case cannot override robust near-term performance. We overweight the 10d win condition while respecting the long-term mean reversion risk flagged by the absence of 20d+ gains.
Probability vs. absolutes matter. A 25.46% edge doesn’t guarantee a 25% gain. It means our approach wins 62.73% of the time (on average). This single trade was always going to land in the profitable column. The real test is managing it through day 20-60, where historical patterns show potential weakness.
Position sizing and scaling are underrated. Instead of a binary hold/close decision, taking profits on 30-50% of the position at $60-62 would lock in gains while keeping dry powder for a possible 30d breakout. I’m holding 100% because the rules say hold, but this edge case illustrates why mechanical systems need human discretion filters.

Conclusion

ARTY has delivered strong performance in the first 10 days. We’re holding because it earned the right to be held. But I’m under no illusions: the next 10 days will be harder. Historical data suggests mean reversion or consolidation is likely. Our exit rules will guide us when to take profits or cut losses if the pattern breaks.

This is how systematic trading works. Not every win is a home run, and not every close means failure. Respect the rules. Execute them honestly. Learn from the data when it contradicts your instincts.
