Practice: will the order fill? Reading orders against wicks

A wick that reaches your price looks like a fill. Sometimes it is, sometimes it is not, and for a stop it is a trigger. Nine real orders, read from the candles.

You will learn
  • Read limit and stop orders against highs and lows
  • Tell a trade through a price from a touch

Before you start: The lesson on market, limit and stop orders.

How it works

Each chart is 24 real hourly candles of BTC/USDT, with an order placed before the first one on the far side of the price: a buy limit or a sell stop below it, a sell limit or a buy stop above it. Say what happened by the end:

  • Filled or triggered — price traded through the order's price (a stop also triggers when price only reaches it).
  • Not filled — price never reached it.
  • Can't tell — price reached a limit's price exactly and turned: it depends on the orders ahead of it.

Then the chart marks how far price went.

Will it fill? — nine real BTC/USDT orders between June and October 2026, each left for 24 hourly candles: limits that filled, limits price only touched, limits never reached, and stops triggered by a single trade at their price.

What it trains

The candles show the highest and lowest trades — enough to tell a sure fill, a sure miss and a trigger, but not who traded at the very extreme. Several of these orders sit at round prices, where many orders wait.

Takeaways
  1. A limit filled for sure only if price traded through it.
  2. A stop triggers when a trade prints at its price.
  3. A touch of a limit's price leaves the fill uncertain.
