Tools.
Small calculators for the arithmetic that sits between a trading idea and an actual order. Free, no account, no email, and the answer appears as you type.
Why these are free
Every one of these does something you could do on paper. Putting them behind a signup would be a way of charging for arithmetic, and it would make the page useless to the person who just wants a number before the market opens.
What is worth paying for is the part that happens when you are not watching. That is what the bots do — they apply rules like these on the broker account you already have, while you are at work. The tools here are the manual version of one small piece of that.
These pages are educational. They compute what you enter and do not offer advice or recommendations. See the risk disclosure.
