Look-ahead bias happens when a test uses information that was not available at the moment being tested, like a revised figure or a future price. It makes backtests look better than they would have been live.
Loss aversion is the tendency to feel losses more strongly than equivalent gains. In trading it shows up as refusing to exit at the stop, because closing makes the loss final. The loss already exists either way.
Market depth shows how much size is waiting behind the best bid and ask. Two markets can have the same top quote and react very differently to a large order. Learn what to check.
Trading on one timeframe is simpler; adding a higher timeframe gives you context. Learn what each setup provides, what it costs, and how to choose based on your style.

A personal trading risk policy is a written set of limits and rules for your trading: how much to risk, what stops you, and what you will not do. It turns risk awareness into a document.

A premarket trading plan settles the decisions that should not be made while the market is moving: the setup to watch, the risk budget, the entry and exit, and the pause rules. Learn what goes in it.

A profitable trade can be a bad decision, and a losing trade can be a good one. Learn to review the process that produced the trade, not the profit it happened to make.
A scenario plan writes down what you will do if several possible things happen. A prediction claims one thing will happen. One supports trading; the other usually misleads it.
An index is a rule set for measuring a basket; an ETF is a tradable product that tries to follow that rule set. Learn the difference and why two products tracking the same index can still differ.
A fixed take-profit closes at a set distance; a trailing exit follows the move and locks in more gain as it runs. Each gives up something. Learn how to choose between them for your style.
