placeOrder took 13 positional arguments; the other five order functions took
9-13. The leading six — adapter, symbol, openOrders, locks, timers, pendings —
were the same values at all 36 call sites, and every engine spelled them out
again for each order it placed.
Introduce Parameter Object: OrderContext holds what is fixed for an engine's
lifetime (exposed once via a lazily-built this.orderContext), and each function
takes a named request. A wrong argument order is now a compile error rather than
a silently misrouted order.
The type change surfaced dead weight: placeOrder's opts.priceTick was never read
by its body, yet five engines passed it. Removed.
Also finishes the PrecisionSyncer migration — grid-engine was the ninth copy and
was missed last round, so it still carried the uncleared retry timer.
Extract Function: normalizeQuantity replaces the round-down-but-never-to-zero
block that appeared in all five order functions.
250 pass; tsc and oxlint clean.
Every engine hand-rolled the same ~35-line syncPrecision: fetch getPrecision(),
compare against a 1e-12 epsilon, log, retry in 2s on failure. The copies had
drifted — three bypassed i18n with hardcoded strings, maker-points alone
supported a forced re-sync, and the maker family wrote this.qtyStep while
trend/swing/guardian wrote config.qtyStep.
Extract Class: PrecisionSyncer owns both increments plus min base/quote amounts
and writes through to config, so both read styles keep working. Engines now hold
one collaborator instead of four fields.
Fixes a leak present in all eight copies: the 2s retry timer was never cleared,
so an engine stopped mid-retry kept polling a dead adapter forever. stop() now
cancels it — in the Ink UI that leaked one retry loop per strategy switch.
Also collapses log.trend.precision*/log.guardian.precision* into log.common.*
(the three key pairs held byte-identical text).
