Intraday Trading: Manual Execution and Spread Costs

Intraday trading means opening and closing positions within the same session. The edge in most intraday methods is small, and execution can take all of it. A trader who pays the spread twice, chases fills and trades in the thinnest minutes of the day can turn a sound idea into a losing record. This course treats execution as a skill you can measure and improve.

When is the best time of day for intraday trading?

It depends on the market, and you can measure it. In most stock markets spreads are widest in the first minutes after the open, narrow through the morning, and volume dries up around midday before rising into the close. The course has you study one market across the session so that your timing comes from data, not from a rule of thumb.

How much do spreads and slippage cost an intraday trader?

Often more than they think. Several round trips a day, each paying half the spread on the way in and on the way out plus commission, can add up to more than the average profit per trade. The course shows you how to calculate this from your own fills and how to lower it with order type, timing and size.

Who is this course for?

Day traders and prop traders who place orders by hand and want to keep more of their edge. No programming is needed.

What you will be able to do

• Describe how spread, volume and volatility change through the trading session in your market.
• Choose between market, limit and stop orders for each intraday situation, and state the cost of each.
• Measure slippage and total cost per trade from your own fills in a spreadsheet.
• Write an intraday execution checklist and show from your record that it lowered your costs.

Syllabus, module by module

1. The trading day

   The open, the midday lull and the close: volume, volatility and spread through the session.

2. Orders by hand

   Market, limit, stop and stop-limit orders, and when each one costs you money.

3. Spread and slippage

   Why the price you see is not the price you get, and how to measure the gap.

4. Depth and the order book

   Reading the bid and offer queue, and what thin depth means for your size.

5. Intraday levels

   The opening range, the prior close, VWAP and the day's high and low.

6. Your execution record

   Cost per trade, slippage by time of day, and the checklist that fixes the worst of it.
