Trading fees: the charge for a trade.
A provider may charge when you enter and when you exit. A rate shown “per side” applies separately to each side. Check the actual market and order type; a commission, a spread, and a funding payment are different things. Vest’s fee schedule.
A low advertised fee is not the whole cost of using a product.
Spread: the gap between buying and selling.
The best available buying and selling prices are usually different. Crossing that gap affects the result of entering and exiting. A quoted price is not a guarantee that your whole order can fill there; the actual fill can differ.
For a beginner, the useful question is simple: what price can I actually enter at, and what price could I exit at? A chart’s last price alone does not answer it.
Funding: a payment while the position is open.
A perp can involve periodic transfers between long and short positions. Under Vest’s convention, a positive funding rate means longs pay shorts; a negative rate reverses that. Vest settles hourly, while other venues may use a different schedule. Official funding explanation.
Funding can change. Receiving a payment does not make a trade profitable or remove price risk. Do not treat a rate displayed now as a promise about tomorrow’s holding cost.
Leverage: more exposure relative to your money.
Margin is the collateral supporting a position. Leverage allows greater exposure relative to that collateral. Changing the leverage setting does not change the price exposure of a position whose size stays the same. Vest’s margin explanation.
As an arithmetic illustration, $1,000 of exposure supported by $100 has 10 times that supporting amount. A 1% adverse price move is $10 before costs—10% of the $100. This is not a margin rule or a liquidation-price calculation.
The provider may close a position if required margin is no longer available. A planned stop does not guarantee the exit price. An account program can also impose separate loss rules.
A short checklist before considering a trade.
Understand the exposure, entry and exit charges, likely holding period, funding convention, market hours, and forced-close rules. If any of those is missing, the product is not yet fully understood.
No format is automatically best for every beginner. Go back to the comparison or the basic definitions whenever a term is unclear.
