Types of orders — market, limit, GTT, and AMO.
Every order type has one job. Know it before you tap 'Buy'.
The stock was ready. Six order types stood between you and the buy button.
You've done the reading. The stock checks out. You open your broker app, tap the buy button, and stare at a dropdown: Market. Limit. Stop-loss. GTT. AMO. Bracket. You just wanted to own the stock. Nobody warned you there'd be an exam first.
Every order is an instruction you send to your broker. It tells the exchange three things: what to trade, how much, and under what conditions.
A market order says: execute right now, at whatever price the market offers. You get speed. You don't get to choose the price. On large, liquid stocks this usually works fine. On a thinly traded small-cap, the price can move against you the moment you tap 'Buy'.
A limit order says: only trade if the price reaches my number. You control the price. But execution isn't guaranteed — if the market never hits your limit, the order sits unfilled. Most long-term investors use limit orders as their default.
A stop-loss fires automatically if a stock falls to your floor price — it's protection against a freefall. A GTT (Good Till Triggered) is a limit or stop-loss that stays alive for months, not just one trading day. An AMO (After Market Order) lets you queue an instruction overnight so it fires when the market opens at 9:15 AM — no alarm, no rushing to your phone.
Mr. Market names a different price daily
Mr. Market is a neighbour with moods. Some days he's euphoric and quotes a high price at your door. Some days he's panicking and will sell the same stock for far less. A market order means you accept whatever he names today, no questions asked. A limit order is the note you leave on the door: 'Come back only when you'll sell for ₹X or lower.' A GTT is that same note — patient, waiting, even while you're away for weeks.
Why this matters
You will place hundreds of orders over your investing life. Getting the order type wrong once on a thinly traded stock can cost you as much as a month of returns — before you've even held the position for a day. A limit order takes ten extra seconds. Those ten seconds are worth taking. GTTs mean you don't need to watch your portfolio every afternoon. Set the parameters once, then live your life. The order type isn't glamorous. It is foundational.
Drag the stop-loss. Watch your maximum loss appear in actual rupees.
The widget below makes stop-losses feel real. Enter your investment amount, drag the stop-loss percentage, and watch the maximum-loss floor appear in actual rupees — so the number stops being abstract and starts feeling like your money.
What does your stop-loss actually protect?
You are putting ₹50,000 into this stock. If it drops 10% from your buy price, the stop-loss order fires automatically and you walk away with ₹45,000. Your worst case is losing ₹5,000 — and knowing that number before you place the trade is exactly what a stop-loss is for.
Most investors need just one order type. The limit order.
Where people go wrong
- Using a market order on a thinly traded stockLow trading volume means the price can jump against you the moment you buy. You pay more than you intended before the order even settles.
- Setting a stop-loss too tightNormal daily price swings can trigger the stop-loss before any real danger arrives. You get forced out of a good position — then watch it recover without you.
- Forgetting a GTT you placed months agoGTTs stay alive for a long time. If you forget one, it can fire on a day you're distracted, at a price that no longer reflects your thinking.
- Placing an AMO without checking corporate actionsOvernight bonuses, splits, or ex-dividend dates change the opening price. Your AMO limit price may be completely stale by 9:15 AM.
A limit order gives you price control. A market order gives you speed. You rarely need both at once.
A GTT waits patiently for weeks or months without you checking. Set it once and let it work.
Long-term investors need almost nothing beyond a limit order and a GTT. Everything else is built for traders.
Loss aversion pushes people to set stop-losses in a panic — then abandon them entirely after one false trigger. They end up with the worst of both worlds: they sold when they shouldn't have, and now they have no floor at all.
