PSX Strategy Optimizer
Backtest dip-buy strategies on Pakistan Stock Exchange historical data — 100% client-side.
The Basic Idea
This is a "buy the dip" strategy. When a stock's price falls from its opening price during the day, you buy at those lower levels. If the price bounces back to your target, you sell for profit. You split your money into parts so you don't put everything in at once — you buy more as it gets cheaper.
Full Example: Buying FFC with PKR 300,000
Let's say you pick these settings after running the optimizer:
Capital = PKR 300,000
Parts = 6
Buy Levels = 1%, 2%, 3%, 4%, 5%
Target = 2%
Step 1 — Split your capital into parts:
PKR 300,000 ÷ 6 parts = PKR 50,000 per part
Step 2 — Calculate buy prices (assuming FFC opens at Rs. 150):
1% drop → 150 × (1 - 0.01) = Rs. 148.50 → spend 50,000 → get 337 shares
2% drop → 150 × (1 - 0.02) = Rs. 147.00 → spend 50,000 → get 340 shares
3% drop → 150 × (1 - 0.03) = Rs. 145.50 → spend 50,000 → get 344 shares
4% drop → 150 × (1 - 0.04) = Rs. 144.00 → spend 50,000 → get 347 shares
5% drop → 150 × (1 - 0.05) = Rs. 142.50 → spend 50,000 → get 351 shares
Step 3 — What actually happens during the day?
A
WIN scenario — Price drops 3% then bounces back:
You triggered buys at 1%, 2%, and 3% levels (3 parts used = PKR 150,000).
Total shares: 337 + 340 + 344 = 1,021 shares
Average buy price: PKR 150,000 ÷ 1,021 = Rs. 146.97
Your target: 146.97 × 1.02 = Rs. 149.91
If the day's HIGH reaches Rs. 149.91 → PROFIT = Rs. 3,002
You triggered buys at 1%, 2%, and 3% levels (3 parts used = PKR 150,000).
Total shares: 337 + 340 + 344 = 1,021 shares
Average buy price: PKR 150,000 ÷ 1,021 = Rs. 146.97
Your target: 146.97 × 1.02 = Rs. 149.91
If the day's HIGH reaches Rs. 149.91 → PROFIT = Rs. 3,002
B
LOSS scenario — Price drops 5% and stays down:
You triggered all 5 buy levels (5 parts used = PKR 250,000).
Total shares: 1,719 shares. Average price: Rs. 145.44
Target: Rs. 148.35 — but the day's HIGH never reaches it.
Market closes at Rs. 143.00 → LOSS = Rs. 4,196
(This is a "stuck day" in the tool's language)

C
NO TRADE scenario — Price never drops 1%:
The day's LOW stays above Rs. 148.50. None of your buy levels trigger.
No profit, no loss — you simply skip the day.
The day's LOW stays above Rs. 148.50. None of your buy levels trigger.
No profit, no loss — you simply skip the day.
How to Actually Trade This on PSX
1
Before market opens (9:00 AM), note your stock's expected opening price (check the pre-open session or previous close).
2
Calculate your buy prices:
Buy Price = Open × (1 - Level%) for each level.3
Place limit buy orders at each calculated price in your brokerage app (KTrade, MyTrade, PSX Edge, or call your broker). Each order amount = Capital ÷ Parts.
4
After your first buy triggers, calculate your average buy price and set a limit sell order at:
Target = Avg Price × (1 + Target%)5
At market close (3:30 PM), if target was NOT hit, sell at closing price to free up capital for next day. Do NOT hold overnight — this is a same-day strategy.
Reading the Results
- Total Profit — How much money you would have made over all days tested. Positive = good.
- Win Rate — Out of all days you traded, what percentage hit the target. Above 60% is solid. Above 70% is excellent.
- Max Loss — Your single worst day. This tells you the worst-case pain. Keep this small.
- Stuck Days — Days where price dropped enough to trigger buys but never bounced to target. These are your risk days. Fewer is better.
- Score — Combined number rewarding high profit + high win rate + low max loss. Higher = better overall.
What the Optimizer Does
Tests many combinations automatically. For example:
[1%,2%,3%,4%] with 1% target → Score: 450
[1%,2%,3%,4%] with 1.5% target → Score: 680
[1%,2%,3%,4%] with 2% target → Score: 820 ← winner
[1%,2%,3%,4,5%] with 1% target → Score: 390
... and so on for all combinations
Then ranks by Score and shows the best combination — that's the one you should use in real trading.
Pro Tip: Always run the optimizer on at least 6-12 months of data. A strategy that looks good on 1 month might fail in another. More data = more reliable results.
Warning: Past performance does NOT guarantee future results. Use small amounts first. Never invest money you can't afford to lose. This tool is for educational and research purposes only.
