Orders & Trading

Overview

The LFG SDK supports various order types for trading perpetual contracts. This guide covers everything from placing basic market orders to managing complex trading strategies.

Short-Term Orders

Fast orders that expire in blocks (~seconds to minutes)

Long-Term Orders

Traditional limit orders with time-based expiration (hours to days)

Order Types

Short-Term Orders

Short-term orders are ideal for:

Market-making strategies
High-frequency trading
Quick in-and-out trades
Time-sensitive opportunities

Characteristics:

Expire based on block height
Lower gas costs
Faster execution
Typical lifespan: seconds to minutes

Long-Term Orders

Long-term orders are ideal for:

Position building
Swing trading
Limit orders that can wait
Strategy orders

Characteristics:

Expire based on timestamp
Standard gas costs
Can stay on orderbook for days
Typical lifespan: hours to 28 days

Placing Short-Term Orders

Basic Short-Term Order

import {
  CompositeClient,
  LocalWallet,
  SubaccountInfo,
  OrderSide,
  Order_TimeInForce,
} from "@oraichain/lfg-client-js";

async function placeShortTermOrder(
  client: CompositeClient,
  wallet: LocalWallet
) {
  // Get current block height
  const currentBlock = await client.validatorClient.get.latestBlockHeight();

  // Order expires in 20 blocks (~2 minutes)
  const goodTilBlock = currentBlock + 20;

  // Generate unique client ID
  const clientId = Math.floor(Math.random() * 100000000);

  // Create subaccount
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);

  // Place BUY order
  const tx = await client.placeShortTermOrder(
    subaccount, // Trading account
    "ETH-USD", // Market
    OrderSide.BUY, // Side
    3800, // Price ($3800/ETH)
    0.1, // Size (0.1 ETH)
    clientId, // Unique order ID
    goodTilBlock, // Expiration block
    Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED, // Time in force
    false // Not reduce-only
  );

  console.log("✅ Order placed!");
  console.log("TX Hash:", Buffer.from(tx.hash).toString("hex"));
  console.log("Client ID:", clientId);

  return { txHash: Buffer.from(tx.hash).toString("hex"), clientId };
}

subaccount

SubaccountInfo

required

The subaccount placing the order

marketId

string

required

Market identifier (e.g., "ETH-USD", "BTC-USD")

side

OrderSide

required

OrderSide.BUY or OrderSide.SELL

price

number

required

Limit price in quote currency (USD). Set to market price for market orders.

size

number

required

Order size in base currency (e.g., ETH, BTC)

clientId

number

required

Unique identifier for this order (0 to 2^32-1)

goodTilBlock

number

required

Block height when order expires. Must be greater than current block.

timeInForce

Order_TimeInForce

required

Order time in force policy. Use TIME_IN_FORCE_UNSPECIFIED for most cases.

reduceOnly

boolean

required

If true, order can only reduce position size (not increase it)

Sell Order Example

// Place SELL order to close or short
const tx = await client.placeShortTermOrder(
  subaccount,
  "ETH-USD",
  OrderSide.SELL, // Selling ETH
  3900, // Sell at $3900
  0.1, // Sell 0.1 ETH
  clientId,
  goodTilBlock,
  Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED,
  false
);

Market Order (Short-Term)

// Get current market price first
const markets = await client.indexerClient.markets.getPerpetualMarkets();
const ethMarket = markets.markets["ETH-USD"];
const marketPrice = parseFloat(ethMarket.oraclePrice);

// Place order at market price
const tx = await client.placeShortTermOrder(
  subaccount,
  "ETH-USD",
  OrderSide.BUY,
  marketPrice, // Use current market price
  0.1,
  clientId,
  goodTilBlock,
  Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED,
  false
);

For true market orders, query the current market price and place a short-term order at that price with a short expiration.

Placing Long-Term Orders

Basic Long-Term Order

import {
  OrderType,
  OrderTimeInForce,
  OrderExecution,
} from "@oraichain/lfg-client-js";

async function placeLongTermOrder(
  client: CompositeClient,
  wallet: LocalWallet
) {
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);

  // Generate unique client ID
  const clientId = Math.floor(Math.random() * 100000000);

  // Order valid for 24 hours
  const goodTilTimeInSeconds = 24 * 60 * 60;

  // Place limit order
  const tx = await client.placeOrder(
    subaccount,
    "ETH-USD", // Market
    OrderType.LIMIT, // Order type
    OrderSide.BUY, // Side
    3800, // Price
    0.1, // Size
    clientId, // Client ID
    OrderTimeInForce.GTT, // Good-til-time
    goodTilTimeInSeconds, // Expires in 24 hours
    OrderExecution.DEFAULT, // Execution type
    false, // Post-only (false)
    false // Reduce-only (false)
  );

  console.log("✅ Long-term order placed!");
  console.log("TX Hash:", Buffer.from(tx.hash).toString("hex"));
  console.log("Client ID:", clientId);
  console.log("Expires in:", goodTilTimeInSeconds, "seconds");

  return { txHash: Buffer.from(tx.hash).toString("hex"), clientId };
}

orderType

OrderType

required

OrderType.LIMIT, OrderType.MARKET, OrderType.STOP_LIMIT, or OrderType.STOP_MARKET

timeInForce

OrderTimeInForce

required

OrderTimeInForce.GTT - Good-til-time (most common) - OrderTimeInForce.IOC - Immediate or cancel - OrderTimeInForce.FOK - Fill or kill

goodTilTimeInSeconds

number

required

Seconds from now until order expires (max 28 days)

execution

OrderExecution

required

OrderExecution.DEFAULT, OrderExecution.POST_ONLY, or OrderExecution.IOC

postOnly

boolean

required

If true, order will only execute as maker (adds liquidity)

reduceOnly

boolean

required

If true, order can only reduce existing position

Post-Only Orders

Post-only orders ensure you’re always a maker:

const tx = await client.placeOrder(
  subaccount,
  "BTC-USD",
  OrderType.LIMIT,
  OrderSide.BUY,
  65000, // Price
  0.01, // Size
  clientId,
  OrderTimeInForce.GTT,
  7 * 24 * 60 * 60, // 7 days
  OrderExecution.POST_ONLY, // Post-only execution
  true, // Post-only flag
  false
);

Post-only orders are rejected if they would immediately match and execute as a taker. This guarantees maker rebates.

Reduce-Only Orders

Reduce-only orders can only close existing positions:

// Close half of your long position
const tx = await client.placeShortTermOrder(
  subaccount,
  "ETH-USD",
  OrderSide.SELL, // Sell to reduce long position
  3900,
  0.05, // Reduce by 0.05 ETH
  clientId,
  goodTilBlock,
  Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED,
  true // Reduce-only = true
);

Reduce-only orders will be rejected if you don’t have an open position in that market.

Canceling Orders

Cancel Short-Term Order

import { OrderFlags } from "@oraichain/lfg-client-js";

async function cancelShortTermOrder(
  client: CompositeClient,
  wallet: LocalWallet,
  clientId: number,
  originalGoodTilBlock: number
) {
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);

  // Cancel with new goodTilBlock
  const tx = await client.cancelOrder(
    subaccount,
    clientId, // Original client ID
    OrderFlags.SHORT_TERM, // Order flag
    "ETH-USD", // Market
    originalGoodTilBlock + 10, // New expiration
    0 // goodTilTimeInSeconds (0 for short-term)
  );

  console.log("✅ Order cancelled!");
  console.log("TX Hash:", Buffer.from(tx.hash).toString("hex"));
}

Cancel Long-Term Order

async function cancelLongTermOrder(
  client: CompositeClient,
  wallet: LocalWallet,
  clientId: number,
  originalGoodTilBlockTime: number
) {
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);

  const currentTime = Math.floor(Date.now() / 1000);
  const timeUntilExpiration = originalGoodTilBlockTime - currentTime;

  const tx = await client.cancelOrder(
    subaccount,
    clientId,
    OrderFlags.LONG_TERM, // Order flag
    "ETH-USD",
    0, // goodTilBlock (0 for long-term)
    timeUntilExpiration + 60 // Add 60 seconds buffer
  );

  console.log("✅ Order cancelled!");
  console.log("TX Hash:", Buffer.from(tx.hash).toString("hex"));
}

To cancel an order, you need the original clientId and order flags. Store these when placing orders.

Querying Orders

Get All Orders for Subaccount

async function getUserOrders(
  client: CompositeClient,
  address: string,
  parentSubaccountNumber: number = 0
) {
  const orders = await client.indexerClient.account.get(
    "/v4/orders/parentSubaccountNumber",
    {
      address,
      parentSubaccountNumber,
      returnLatestOrders: true,
    }
  );

  for (const order of orders) {
    console.log(`Order ${order.id}:`);
    console.log(`  Market: ${order.ticker}`);
    console.log(`  Side: ${order.side}`);
    console.log(`  Price: $${order.price}`);
    console.log(`  Size: ${order.size}`);
    console.log(`  Filled: ${order.totalFilled}`);
    console.log(`  Status: ${order.status}`);
  }

  return orders;
}

Filter Orders by Market

const ethOrders = await client.indexerClient.account.get(
  "/v4/orders/parentSubaccountNumber",
  {
    address: wallet.address,
    parentSubaccountNumber: 0,
    ticker: "ETH-USD", // Filter by market
    returnLatestOrders: true,
  }
);

Filter Orders by Status

import { OrderStatus } from "@oraichain/lfg-client-js";

// Get only open orders
const openOrders = await client.indexerClient.account.get(
  "/v4/orders/parentSubaccountNumber",
  {
    address: wallet.address,
    parentSubaccountNumber: 0,
    status: OrderStatus.OPEN, // Filter by status
    returnLatestOrders: true,
  }
);

Get Order by ID

async function getOrderById(client: CompositeClient, orderId: string) {
  const order = await client.indexerClient.account.getOrder(orderId);

  console.log("Order Details:");
  console.log(`  ID: ${order.id}`);
  console.log(`  Client ID: ${order.clientId}`);
  console.log(`  Market: ${order.ticker}`);
  console.log(`  Side: ${order.side}`);
  console.log(`  Type: ${order.type}`);
  console.log(`  Price: $${order.price}`);
  console.log(`  Size: ${order.size}`);
  console.log(`  Filled: ${order.totalFilled}`);
  console.log(`  Status: ${order.status}`);
  console.log(`  Created: ${order.createdAt}`);

  return order;
}

Advanced Trading Strategies

Grid Trading Bot

async function setupGridOrders(
  client: CompositeClient,
  wallet: LocalWallet,
  market: string,
  basePrice: number,
  gridLevels: number,
  gridSpacing: number,
  orderSize: number
) {
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);
  const currentBlock = await client.validatorClient.get.latestBlockHeight();
  const goodTilBlock = currentBlock + 100;

  const orders = [];

  // Place buy orders below base price
  for (let i = 1; i <= gridLevels; i++) {
    const price = basePrice * (1 - gridSpacing * i);
    const clientId = Math.floor(Math.random() * 100000000);

    const tx = await client.placeShortTermOrder(
      subaccount,
      market,
      OrderSide.BUY,
      price,
      orderSize,
      clientId,
      goodTilBlock,
      Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED,
      false
    );

    orders.push({ side: "BUY", price, clientId, txHash: tx.hash });
  }

  // Place sell orders above base price
  for (let i = 1; i <= gridLevels; i++) {
    const price = basePrice * (1 + gridSpacing * i);
    const clientId = Math.floor(Math.random() * 100000000);

    const tx = await client.placeShortTermOrder(
      subaccount,
      market,
      OrderSide.SELL,
      price,
      orderSize,
      clientId,
      goodTilBlock,
      Order_TimeInForce.TIME_IN_FORCE_UNSPECIFIED,
      false
    );

    orders.push({ side: "SELL", price, clientId, txHash: tx.hash });
  }

  console.log(`✅ Placed ${orders.length} grid orders`);
  return orders;
}

// Usage
await setupGridOrders(
  client,
  wallet,
  "ETH-USD",
  3800, // Base price
  5, // 5 levels on each side
  0.01, // 1% spacing
  0.01 // 0.01 ETH per order
);

Stop-Loss Order

async function placeStopLossOrder(
  client: CompositeClient,
  wallet: LocalWallet,
  market: string,
  stopPrice: number,
  size: number
) {
  const subaccount = SubaccountInfo.forLocalWallet(wallet, 0);
  const clientId = Math.floor(Math.random() * 100000000);

  const tx = await client.placeOrder(
    subaccount,
    market,
    OrderType.STOP_MARKET, // Stop order
    OrderSide.SELL, // Sell to close long
    stopPrice, // Trigger price
    size,
    clientId,
    OrderTimeInForce.GTT,
    7 * 24 * 60 * 60, // Valid for 7 days
    OrderExecution.DEFAULT,
    false,
    true, // Reduce-only
    stopPrice // triggerPrice parameter
  );

  console.log("✅ Stop-loss order placed at $" + stopPrice);
  return tx;
}

Best Practices

Generate Unique Client IDs

Always use unique client IDs for each order:

const clientId = Date.now() * 1000 + Math.floor(Math.random() * 1000);

Or use a counter with your bot instance:

let orderCounter = 0;
const clientId = orderCounter++;

Handle Order Expiration

Short-term orders expire quickly. Always check if enough blocks remain:

const currentBlock = await client.validatorClient.get.latestBlockHeight();
const minBlocksNeeded = 10;

if (goodTilBlock < currentBlock + minBlocksNeeded) {
  // Order would expire too soon, refresh goodTilBlock
  goodTilBlock = currentBlock + 20;
}

Store Order Metadata

Keep track of your orders for cancellation and monitoring:

interface OrderMetadata {
  clientId: number;
  orderId?: string;
  market: string;
  side: OrderSide;
  price: number;
  size: number;
  goodTilBlock?: number;
  goodTilBlockTime?: number;
  orderFlags: OrderFlags;
  createdAt: Date;
}

const orderHistory: OrderMetadata[] = [];

Implement Order Retry Logic

Network issues can cause order placement to fail:

async function placeOrderWithRetry(
  maxRetries: number = 3
): Promise<any> {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await client.placeShortTermOrder(/* ... */);
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
    }
  }
}
