How to make limit order via Swift API?

[vavdoshka]

Hello,

I'm trying to use swift api to submit limit orders but failed to do so. The request passes with 200 response { message: 'Order processed' } but the order is never created. I narrowed down the problem to the order parameters, because I can create orders for market auction order from documenation sample just fine.
Also I can create the classical limit order with the same parameters without an issue, but I want to migrate to swift api.

Here is the sample to reproduce the issue

import { Connection } from "@solana/web3.js";
import { BN, DriftClient, getLimitOrderParams, loadKeypair, MarketType, PositionDirection, Wallet, generateSignedMsgUuid, OrderParams } from "@drift-labs/sdk";
import axios from "axios";

import dotenv from "dotenv";
dotenv.config();


async function main() {
    const wallet = new Wallet(loadKeypair(process.env.PRIVATE_KEY!));

    const driftClient = new DriftClient({
        connection: new Connection(process.env.SOLANA_RPC_URL!),
        wallet: wallet,
        env: "mainnet-beta",
        userStats: false,
        activeSubAccountId: 0,
        perpMarketIndexes: [0],
        spotMarketIndexes: [0],
        subAccountIds: [0],
        includeDelegates: false,
        skipLoadUsers: false,
        accountSubscription: {
            type: "websocket",
            resubTimeoutMs: undefined,
            logResubMessages: false,
        },

    });

    await driftClient.subscribe();

    const marketIndex = 0;

    const oracleInfo = driftClient.getOracleDataForPerpMarket(marketIndex);
    const lowPrice = oracleInfo.price;
    const highPrice = oracleInfo.price.muln(101).divn(100);
    const direction = PositionDirection.LONG;


    // these order params working well - order created
    // const orderParams = getMarketOrderParams({
    //     marketIndex: marketIndex,
    //     marketType: MarketType.PERP,
    //     direction: PositionDirection.LONG,
    //     baseAssetAmount: driftClient.convertToPerpPrecision(0.1), // 0.1 SOL,
    //     auctionStartPrice: isVariant(direction, 'long') ? lowPrice : highPrice,
    //         auctionEndPrice: isVariant(direction, 'long') ? highPrice : lowPrice,
    //         auctionDuration: 50,
    // });

    // these order params dont work - order not created
    const orderParams = getLimitOrderParams({
        marketType: MarketType.PERP,
        marketIndex,
        direction,
        baseAssetAmount: driftClient.convertToPerpPrecision(0.1),
        price: lowPrice,
    });

    const slot = await driftClient.connection.getSlot();

    const orderMessage = {
        signedMsgOrderParams: orderParams as OrderParams,
        subAccountId: driftClient.activeSubAccountId,
        slot: new BN(slot),
        uuid: generateSignedMsgUuid(),
        stopLossOrderParams: null,
        takeProfitOrderParams: null,
    };

    const { orderParams: message, signature } = driftClient.signSignedMsgOrderParamsMessage(orderMessage);


    const swiftUrl = 'https://swift.drift.trade/orders';

    const response = await axios.post(swiftUrl, {
        market_index: marketIndex,
        market_type: 'perp',
        message: Buffer.from(message).toString('utf8'),
        signature: Buffer.from(signature).toString('base64'),
        taker_authority: driftClient.wallet.publicKey.toBase58(),
    }, {
        headers: { 'Content-Type': 'application/json' }
    });

    console.log("response", response.data);

    process.exit(0);
}

main();

@vavdoshka apologies you are having difficulties. Please add 30 as a buffer to the slot in the case of no auction. If you are doing a resting limit order, it's best to still use the current slot + 30.

If that doesn't work, please share your pubkey with me so I can debug logs. We can DM in that case.

@vavdoshka just wanted to check back in with you. Any luck with adding the buffer?

[vavdoshka]

thanks @LukasDeco, unfortunately

const slot = await driftClient.connection.getSlot() + 30;

did not help to make it, same behaviour

are you on TG or in our discord? On TG I am @LukasDeco. You can message me your pubkey. Or you can open a ticket in our discord: https://discord.com/invite/fMcZBH8ErM

Share your pubkey and then I can look at logs.

For the record, we got Vlad's code to work after adding a buffer of 50 on the slot.
