1 Connection & API Errors

Connection problems are among the most common bot issues. Here are typical scenarios and their solutions:

API Connection Failure

Bot cannot establish connection with exchange APIs

Possible Causes

Invalid API credentials
Expired or revoked API keys
Exchange server maintenance
Network connectivity issues
Firewall blocking connections

Solutions

1 Go to your exchange and copy/paste the API key again
2 Make sure "Spot Trading" is enabled in API permissions
3 Try opening the exchange website – if it loads, your internet is fine
4 Stop and restart the bot
5 If it still fails, create new API keys at your exchange

Prevention Tip

Set up monitoring alerts for API connectivity and regularly check that API keys have not expired.

Rate Limit Exceeded

Too many API requests sent to the exchange in a short period

Possible Causes

Bot makes requests too frequently
Multiple bots use the same API key
Inefficient API usage patterns
Exchange rate limits have changed

Solutions

1 Increase the delay between orders to 5-10 seconds in your bot settings
2 If you have multiple bots, temporarily stop some of them
3 Wait 10-15 minutes before trying again
4 Check if your exchange updated its rate limits
5 Use only one bot per API key pair

Prevention Tip

Monitor API usage and stay well below exchange rate limits. Use efficient batching for multiple requests.

Authentication Failure

Exchange rejects API credentials or signature verification fails

Possible Causes

Incorrect API secret
System clock not synchronized
Invalid request signature
Insufficient API permissions
IP address not whitelisted

Solutions

1 Delete current API keys and create completely new ones
2 Ensure your computer clock is correct (check time/date settings)
3 Double-check you copied the API secret correctly (no extra spaces)
4 Go to exchange API settings and enable all required permissions
5 Add your current IP address to the exchange whitelist

Prevention Tip

Keep system time synchronized and regularly audit API key permissions and IP restrictions.

Timeout Errors

Requests to the exchange API take too long to complete

Possible Causes

Weak network connection
Exchange server overload
Request timeout too short
Geographical distance to servers
ISP routing issues

Solutions

1 Check your internet speed – you need a stable connection for trading
2 Try using a different server region in bot settings
3 Restart your router/modem and wait 2 minutes
4 Close other apps using lots of internet (streaming, downloads)
5 Contact your ISP if problems persist

Prevention Tip

Use appropriate timeout values and implement robust retry mechanisms for network requests.

2 Order Execution Errors

Order-related errors can prevent the bot from executing trades properly. Here are the most common problems:

Balance Issues

Insufficient Balance

High

Not enough funds in your account to place this order

Quick Fix

Either deposit more funds or reduce the order size in bot settings

Account Locked

Critical

Your exchange account has been restricted or suspended

Quick Fix

Log in to your exchange account and check notifications or contact their support

Asset Unavailable

Medium

Selected trading pair is temporarily unavailable

Quick Fix

Choose a different trading pair or wait for the exchange to fix the issue

Order Parameters

Invalid Order Size

Medium

Order amount below minimum or above maximum limits

Quick Fix

Adjust order size to meet exchange requirements

Invalid Price

Medium

Order price outside acceptable range

Quick Fix

Use current market price or adjust price range

Unsupported Order Type

Exchange experiencing high traffic

Quick Fix

Retry with longer delays between attempts

Database Error

High

Exchange database temporarily unavailable

Quick Fix

Wait and retry, or switch to backup exchange

3 Configuration & Settings Errors

Incorrect bot configuration is a common source of errors. These issues often prevent the bot from starting or cause unexpected behavior:

Bot Won’t Start

Very Common

Bot fails to initialize or crashes immediately after starting

Symptoms

Bot status remains offline
Error messages in startup logs
Configuration validation failures
Missing required parameters

Step-by-Step Fix

1 Make sure all required fields are filled (API key, secret, etc.)
2 Go to your exchange and check that the API key is still valid
3 Check that the selected trading pair actually exists
4 Make sure your numbers make sense (not negative, not too small)
5 Look at error messages in the bot’s log section
6 Try resetting the bot to default settings and start again

Verification

Bot should show online status and start monitoring market data without errors.

Incorrect Trading Behavior

Common

Bot runs but does not trade as expected

Symptoms

No orders placed despite signals
Orders placed at wrong prices
Unexpected position sizes
Strategy does not follow configured rules

Step-by-Step Fix

1 Double-check all strategy settings match your intentions
2 Look at what signals your bot receives and why it’s not trading
3 Make sure position sizes are not too small or too large
4 Try your strategy in paper trading mode first to see if it works
5 Compare what your bot does now vs. what you expected
6 Change settings based on current market conditions

Verification

Bot behavior should match strategy expectations and backtest results.

Risk Management Not Working

Serious

Stop losses or risk controls fail to execute properly

Symptoms

Stop losses do not trigger
Position sizes exceed limits
Daily loss limits not enforced
Risk parameters are ignored

Step-by-Step Fix

1 Go to risk settings and make sure they are enabled
2 Test stop loss by placing a small order to see if it works
3 Check that position size limits are actually set
4 Try risk controls with small amounts first
5 Look at recent trades to see if stops triggered correctly
6 Adjust risk settings if markets have become more volatile

Verification

All risk controls should activate properly when tested with small positions.

Performance Degradation

Moderate

Bot performance declines over time

Symptoms

Win rate decreasing
Increasing drawdowns
Strategy signals less effective
Market conditions no longer suitable

Step-by-Step Fix

1 Look at the bot’s recent win/loss record to see what’s wrong
2 Check if market conditions have changed significantly
3 Try adjusting bot settings to current market behavior
4 Consider switching to a different trading strategy
5 Reduce position sizes until performance improves
6 Maybe pause trading until you figure out what’s wrong

Verification

Performance metrics should show improvement or stabilization after adjustments.
