Symmio Trading-SDK — the SDK surface for builders on HyperEVM
CoreTP/SLvalidateTpSl

validateTpSl

Validate a candidate TP/SL pair against the handler’s published rules. Pure and framework-agnostic — a Node script or a Vue app can share it with the React form. The SDK does not throw here; the caller decides whether to surface, block, or proceed.

Checks, in order:

  1. Sign rule — TP above/below the reference price per side; SL the opposite.
  2. minPriceDistancePercent — |target − open| / open × 100 must clear the floor.
  3. minProfitStopLossSpreadPercent — when both sides are set, the absolute TP↔SL spread as a percent of the reference price must clear the floor.
import { validateTpSl } from "@symmio/trading-core";
 
const result = validateTpSl({
  takeProfitPrice: "150",
  stopLossPrice: "80",
  openPrice: "100",
  positionType: PositionType.LONG,
  pricePrecision: 4,
  config: tpslConfig,
});
if (!result.ok) {
  console.log(result.tpError, result.slError);
}

Parameters

A single ValidateTpSlInputs object:

openPricestringrequired

Reference price the distance/spread rules are measured against (decimal string).

positionTypePositionTyperequired

Quote direction (LONG / SHORT).

pricePrecisionnumberrequired

Market price precision — used to render the “should be above/below X” hint.

configTpSlConfigrequired

Live handler /configs/ data.

takeProfitPricestringoptional

TP trigger price (decimal string). Omit when only setting an SL.

stopLossPricestringoptional

SL trigger price (decimal string). Omit when only setting a TP.

isOpenPositionbooleanoptional

When true, error text says “current price” instead of “open price”.

Returns

TpSlValidation

{ ok: true } when every supplied side passes; otherwise { ok: false } with per-side tpError / slError strings.
