Limit-if-Touched (LIT) Order¶
OVERVIEW¶
A Limit-if-Touched (LIT) order is a conditional order that remains dormant until the market price reaches a predetermined trigger level. Once triggered, it automatically submits a standard limit order at the specified limit price. LIT orders give traders strict price control over execution while fully automating the entry trigger.
Note
Unlike a Market-if-Touched (MIT) order, which prioritizes immediate execution and accepts slippage, a LIT order guarantees the trader pays no more than the specified limit price after the trigger fires.
HOW IT WORKS¶
A LIT order requires three inputs:
| Input | Description |
|---|---|
| Trigger Price | The price level that activates the order |
| Limit Price | The maximum (buy) or minimum (sell) acceptable execution price |
| Quantity | Number of shares or contracts to trade |
The order rests off the public order book in the exchange routing system. The exchange monitors the asset's Last Sale price continuously.
Buy LIT logic
- Trigger price is set below the current market price
- When the asset trades down to or through the trigger price, a buy limit order is submitted at the limit price
- The limit price is typically set at or slightly below the trigger price
Sell LIT logic
- Trigger price is set above the current market price
- When the asset trades up to or through the trigger price, a sell limit order is submitted at the limit price
Tip
If the market moves too fast after triggering, the resulting limit order rests on the book and waits for a matching price rather than chasing the market.
WORKED EXAMPLE¶
Scenario: MSFT is trading at $400.00. A trader wants to buy 100 shares if the stock drops to $395.00 but refuses to pay more than $395.00.
Order parameters:
| Parameter | Value |
|---|---|
| Order type | Buy LIT |
| Trigger price | $395.00 |
| Limit price | $395.00 |
| Quantity | 100 shares |
Outcome A — Market reverses immediately
MSFT touches $395.00 and bounces to $395.05. The limit order rests on the book unfilled. The trader misses the trade.
Outcome B — Market continues lower
MSFT touches $395.00 (trigger fires), then continues to $394.90. The limit order executes 100 shares at $394.90, delivering a better-than-expected fill.
WHEN TO USE¶
| Use Case | Description |
|---|---|
| Support level entries | Automate buys at technical support overnight without monitoring the screen |
| Resistance level exits | Submit sell LIT orders above resistance to capture breakout pops |
| Institutional scaling | Trigger limit orders at successive support levels to build large positions without moving the market |
| Algorithmic strategies | Automate dip-buying or rally-selling logic without manual intervention |
LIMITATIONS¶
Note
A LIT order does not guarantee a fill. It only guarantees that if a fill occurs, it will be at or better than the limit price.
| Limitation | Detail |
|---|---|
| Execution uncertainty | If the market triggers the order and immediately reverses, the trade may never fill |
| No fill guarantee | The limit order only executes if the market remains at or beyond the limit price long enough to match |
| Confusion with stop-limit orders | A buy stop-limit triggers when price moves up to the stop price; a buy LIT triggers when price moves down to the touch price |
