Testing

• I have run make test and all checks pass

One fix needed before merging: int64(amount * 1000000) truncates toward zero due to IEEE-754 float representation. For example, 100.2 * 1000000 = 100199999.999... → int64(...) = 100199999 instead of 100200000.

Change to:

import "math"

Ntli: int64(math.Round(amount * 1000000)),

Everything else is correct — the type change, the scaling, and preserving the sign (docs confirm ntli sign controls add/remove direction; isBuy has no effect until hedge mode).

Dismissing — review was premature, pending further analysis.
