Cookie · Tradetron's strategy-building AI

Describe your
trading strategy.
Your AI builds it.

Describe an idea in plain English. Cookie, Tradetron's AI, writes it on a strategy card you can check line by line, then has it built in your Tradetron account — no code. Test your edge before you risk a single dollar, then let it trade your own broker account without the fear or FOMO.

Plain English. We copy it for you to paste on the next page, where Cookie turns it into a strategy card.

The strategy card is free. Builds are free during the US launch campaign (list price $50 per strategy).

Free US strategy templates, tested honestly

Every template was backtested and then charged realistic US costs. These are the ones that still worked; the rest are listed on the templates page, with their real numbers.

Featured only if it makes money after realistic US costs, its closed-trade max drawdown stayed within the capital, and its full backtest report (at the engine's default costs) does not show a loss. Ranked by net P&L after costs divided by closed-trade max drawdown; a template needs at least 100 trades to rank on that score.

#1 Weekly put selling · Cash-secured Free

QQQ Cash-Secured Put, Weekly (Wheel Step 1)

Every Monday, sell one QQQ put near -0.25 delta on the Friday expiry with the strike value held in cash. Buy it back at 50% of the credit, at 3x, or before expiry.

Survives costs: 116 puts cost $397 (7% of the gross). Closed-trade max drawdown stayed at 1.7% of the cash secured.

Capital: The strike value held in cash (up to $74,100).

Interest earned on the cash held to secure the puts is not modelled.

Cost assumptions: SPY/QQQ options: $1.71 per contract per side ($0.65 commission + $1.00 slippage, $0.01 per share, + $0.06 estimated OCC, ORF and FINRA TAF fees). Costs are applied to every fill after the backtest, because the backtest engine cannot model US commissions and exchange fees. The $0.06 per option contract per side for OCC clearing, the options regulatory fee (ORF) and FINRA TAF is an estimate. Not included: the SEC fee and FINRA TAF on share sales, and interest on idle cash.

Hypothetical performance: simulated on historical data, not actual trading, and designed with hindsight; liquidity and fills may differ. No account will necessarily achieve similar results. Past performance does not guarantee future results. Full notice on this page.

The full report's own net: $5,312. It differs from this card because the report charges the backtest engine's default costs (slippage of 0.05% of each fill's value, no commission) instead of the US costs above.

#2 Covered call · Shares + weekly calls Free

SPY Covered Call, Weekly, Trend-Filtered

Hold 100 SPY shares while the hourly trend is up and sell a 0.20-delta Friday call each Monday. The call is always closed before expiry.

Survives costs, but simply holding 100 SPY shares over the same window made about +$23,700.

Capital: 100 SPY shares paid in full at the window's high (about $779), no margin borrowing.

Cost assumptions: SPY options $1.71 per contract per side ($0.65 commission + $1.00 slippage + $0.06 estimated OCC, ORF and FINRA TAF fees); SPY shares no commission, $0.01 per share slippage per side. Costs are applied to every fill after the backtest, because the backtest engine cannot model US commissions and exchange fees. The $0.06 per option contract per side for OCC clearing, the options regulatory fee (ORF) and FINRA TAF is an estimate. Not included: the SEC fee and FINRA TAF on share sales, and interest on idle cash.

Hypothetical performance: simulated on historical data, not actual trading, and designed with hindsight; liquidity and fills may differ. No account will necessarily achieve similar results. Past performance does not guarantee future results. Full notice on this page.

The full report's own net: $851. It differs from this card because the report charges the backtest engine's default costs (slippage of 0.05% of each fill's value, no commission) instead of the US costs above.

#3 Weekly short strangle · Undefined risk Free

QQQ Weekly Short Strangle by DTE

Sell a 0.16-delta QQQ strangle 3-4 days before the Friday expiry. Take 50% of the credit, stop at 2x, close the day before expiry.

Survives costs: few trades keep costs at 26% of the gross +$3,389. Closed-trade max drawdown stayed at 12% of the $14,500 capital.

Capital: Reg-T naked QQQ strangle at 20% less OTM on the larger side + both premiums; max $14,115 (QQQ 753)

Cost assumptions: SPY/QQQ options: $1.71 per contract per side ($0.65 commission + $1.00 slippage, $0.01 per share, + $0.06 estimated OCC, ORF and FINRA TAF fees). Costs are applied to every fill after the backtest, because the backtest engine cannot model US commissions and exchange fees. The $0.06 per option contract per side for OCC clearing, the options regulatory fee (ORF) and FINRA TAF is an estimate. Not included: the SEC fee and FINRA TAF on share sales, and interest on idle cash.

Hypothetical performance: simulated on historical data, not actual trading, and designed with hindsight; liquidity and fills may differ. No account will necessarily achieve similar results. Past performance does not guarantee future results. Full notice on this page.

The full report's own net: $3,360. It differs from this card because the report charges the backtest engine's default costs (slippage of 0.05% of each fill's value, no commission) instead of the US costs above.

Hypothetical performance notice. Hypothetical or simulated performance results have certain limitations. Unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under- or over-compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. Past performance does not guarantee future results. Each linked report charges the backtest engine's default costs, not the US costs on these cards; every card prints the report's own net beside its link.

The part that matters

Your money. Your broker. Your control.

The single most common question we get is "is my money safe?" Here's the honest answer: we never hold it.

[ 01 ] Funds never leave your account

Every order is placed into your own brokerage via its official API. Tradetron never custodies, withdraws, or even touches your capital.

[ 02 ] Kill it in one click

Pause, exit, or sever the broker link instantly — from any device. You are never locked in, and you're always the one holding the off switch.

[ 03 ] Regulated brokers only

You connect only to regulated US brokerages through their official APIs. Trading carries risk; past performance never guarantees future results.

More ways in

Use Tradetron from the AI you already pay for.

Add Tradetron as a custom connector in Claude, ChatGPT, or anything else that speaks MCP. One URL, signed in once, and the tools are in every chat. It runs on the AI subscription you already pay for — Tradetron charges nothing for the connector.
