Why these exist

Every one of them answers a question that costs money when it is guessed: how large the position should be, what the swap will actually fill at, where the venue will close the position for you, what the fees really come to over a year. The arithmetic is simple enough to do by hand and almost nobody does, which is precisely why the errors are so consistent.

Use them together

A normal sequence before a leveraged trade: size the position from the stop, check the liquidation distance against the asset's daily range, and annualise the funding cost if it will be held for days. Before a DEX swap: compute price impact from the real pool reserves, then set slippage tolerance just above it rather than at a comfortable round number.
