I just sent you an email with a confirmation link. Click it and the chapter lands immediately.
If it isn't there in a minute or two, check promotions or spam. A first email from a sender you have never heard from usually lands there, and it is the single most common reason people never get the thing they asked for.
While you wait, the part the chapter assumes you already have
The chapter builds the risk layer. It assumes a signal is already reaching your code exactly once, which is its own problem and the place most people stall.
A duplicated alert opens the position twice. A dropped one leaves it open. Both fail quietly, and neither shows up until something is slow, which is usually the first moment the market is moving.
That is the bridge: a TradingView alert, authenticated, de-duplicated, and written down somewhere that survives a crash. It acknowledges in about two milliseconds against a three second timeout, so a slow broker cannot become a missed signal. 128 passing tests, no network and no broker account needed to run them.
It records only, until you deliberately turn trading on. A misconfigured deploy fails toward watching rather than toward trading unsupervised.
What it is not: it is not a strategy, it will not tell you what to trade, and it does not make a bad system profitable. It is the plumbing, and the plumbing is the part that quietly costs people money.
If you already have a signal path you trust, you do not need this, and I would rather say so here than take nine dollars from someone who did not need it.
