This is the friendliest place to start with a structured exit. You’ll take a classic moving-average crossover and bolt on a fixed dollar stop and a fixed dollar target — the two most common ways traders cap a loss and book a win. By the end you’ll have a saved strategy, a backtest, and a feel for how changing the stop and target reshapes the results.
You’ll learn: an EMA(9)/EMA(21) crossover entry, a $500 stop and $1,000 target, and how to read the exit reasons. Time: about five minutes.

​
The idea, in one sentence

When the fast moving average crosses up through the slow one, momentum has turned up — go long. Then risk $500 to make $1,000 on each trade: a 2-to-1 reward-to-risk shape.

​
Step 1 — Describe it

Open a new chat and type the idea exactly as you’d say it to another trader:
Buy ES on an EMA(9)/EMA(21) cross with a 500stopanda500 stop and a 1,000 target.
That’s the whole prompt. You don’t pick bar sizes, date ranges, or directions — AskFutures fills in sensible defaults and shows you what it chose.
Because you didn’t say otherwise, AskFutures applies its silent defaults: the last 1 year of data, Day Trading on 1-minute bars, and an end-of-day exit so no position is carried overnight. It also makes the strategy both directions unless you ask for long-only. Want longs only? Just add “longs only” to the prompt.

​
Step 2 — Read the strategy card

AskFutures builds the strategy and shows you a card. Skim it before you backtest — this is where you confirm it understood you.
1

Market

ES (E-mini S&P 500). See choosing a symbol if you’d rather trade the micro, MES.
2

Entry rule

Go long when the 9-period EMA crosses above the 21-period EMA. Because the strategy is both-directions by default, it also goes short on the opposite cross.
3

Exit rules

A 500stoploss∗∗,a∗∗500 stop loss**, a **1,000 profit target, and an end-of-day close — whichever comes first. These are structured exits; see risk & trade management.
4

Parameters

The tunable numbers are surfaced for you — typically ema_fast = 9, ema_slow = 21, stop_loss = 500, and target = 1000. These are exactly what the optimizer can sweep later.
The card also includes a Strategy Flow chart so you can see the logic at a glance:
Check the Assumptions and Issues notes on the card. That’s where AskFutures tells you what it inferred (for example, the 1-minute bars) and flags anything it couldn’t add — so you’re never guessing.

​
Step 3 — Run the backtest

Ask for it in plain English:
Backtest it.
A fixed, deterministic engine replays a year of real ES prices one bar at a time, applying your exact rules. It reports P&L, win rate, drawdown, and a full trade list — each trade tagged with why it closed (stop, target, or session close). The same rules on the same data always produce the same numbers; the AI never invents results.
Backtest results are hypothetical and simulated. No real trades were placed, so live outcomes can differ (liquidity, slippage, and execution delays are not the same as a replay). Reported P&L is net of modeled slippage (default 1 tick) and commission (default $2.50/side for full-size ES). Past performance — actual or simulated — does not guarantee future results. Always test before you trade.

​
Step 4 — Read the exit mix

The single most useful thing on the results panel for this strategy is how the trades ended. Sort or scan the trade list by exit reason:
  • Lots of target exits means the 2-to-1 shape is doing its job.
  • Lots of stop exits means the entry is catching too many false crosses.
  • Lots of session close exits means trades are still open at the bell — the stop and target are spaced wide relative to a single day’s range.
That mix tells you what to change next.

​
Step 5 — Iterate

Keep chatting. Each edit becomes a new saved version you can compare side by side.
Change the stop to 300andthetargetto300 and the target to 900.
A tighter stop usually means more stop exits but smaller losers — watch whether win rate falls faster than the average loss shrinks.
Only take long trades.
Useful when you only want to trade with an up-cross and ignore the shorts.
Only go long when the 50-period EMA is rising.
Thinning out counter-trend crosses is the classic next move. See signals & indicators.
This example is illustrative, not a recommendation. A bare EMA crossover is one of the most-tested ideas in trading and is not, on its own, profitable. The point is to show you the build-backtest-iterate loop, not to hand you an edge.
