Adding Crypto Loss Notification to Users on Trading Platform

[Yash Smithh]

Hello,

I’m developing a crypto exchange and trading platform and would like to implement a feature that sends notifications to users when they incur a loss on their trade. For example, if a user buys a cryptocurrency and the price drops below their purchase price, they should receive a notification about the loss.

Here’s what I’m thinking so far, and I’d appreciate any suggestions on improving the logic or integrating it:

 

app.post("/place-order", async (req, res) => {
    try {
        const { userId, orderType, cryptoCurrency, amount, price } = req.body;
        const user = await User.findById(userId);
        
        if (!user) {
            return res.status(404).json({ error: "User not found" });
        }

        if (orderType === "buy" && user.balance < amount * price) {
            return res.status(400).json({ error: "Insufficient balance" });
        }

        if (orderType === "sell" && user.cryptoBalance[cryptoCurrency] < amount) {
            return res.status(400).json({ error: "Insufficient crypto balance" });
        }
        
        // Deduct or add crypto balance based on order type
        if (orderType === "buy") {
            user.balance -= amount * price;
            user.cryptoBalance[cryptoCurrency] += amount;
        } else {
            user.balance += amount * price;
            user.cryptoBalance[cryptoCurrency] -= amount;
        }
        
        // Check for loss after the trade and notify the user
        const currentPrice = await getCryptoPrice(cryptoCurrency); // Function to get the current market price
        const loss = (orderType === "buy" && currentPrice < price) || (orderType === "sell" && currentPrice > price);
        
        if (loss) {
            const lossPercentage = ((price - currentPrice) / price) * 100;
            sendLossNotification(user, lossPercentage);  // Function to send loss notification to the user
        }
        
        await user.save();
        
        res.status(200).json({ message: "Order placed successfully" });
    } catch (error) {
        console.error("Error placing order:", error);
        res.status(500).json({ error: "Internal Server Error" });
    }
});

// Function to send loss notification
function sendLossNotification(user, lossPercentage) {
    // Logic to send notification to the user
    const message = `You have incurred a loss of ${lossPercentage.toFixed(2)}% on your recent trade.`;
    // Example of sending notification (via email or in-app notification)
    // sendEmail(user.email, "Crypto Loss Notification", message);
    console.log(message);  // For now, logging it
}

 

Steps I’ve Taken:

• I added a simple check for price loss after each trade.
• I’ve created a sendLossNotification function to notify the user via an email or in-app notification.

Has anyone implemented a similar notification feature? Any tips on improving the logic or integrating it with a notification system?

Thanks in advance!

Adding a crypto loss notification feature is a great way to keep users informed and enhance the user experience on your trading platform. To implement this efficiently, consider partnering with a professional crypto exchange app development services like Dev Technosys. They can integrate real-time notifications and other valuable features to keep users updated on market changes and potential losses.

Good Thinking to send a notification to the user regarding their crypto loss Crypto trading apps like Binance, WazirX, Coinbase should add this feature and blockchain development company who develop appslike these also add this feature to their apps.

Adding a Crypto Loss Notification feature to a trading platform helps users stay informed about their portfolio performance. This feature can send real-time alerts when a user's crypto holdings drop below a certain threshold
