-# Solana Sniper Bot (Poc)
-This code is written as proof of concept to demonstrate how we can buy new tokens immediately after the liquidity pool is open for trading.
+# Solana Trading Bot (Beta)
+The Solana Trading Bot is a software tool designed to automate the buying and selling of tokens on the Solana blockchain. 
+It is configured to execute trades based on predefined parameters and strategies set by the user. 
 
-Script listens to new Raydium USDC or SOL pools and buys tokens for a fixed amount in USDC/SOL.  
-Depending on the speed of the RPC node, the purchase usually happens before the token is available on Raydium UI for swapping.
-
-This is provided as is, for learning purposes.
+The bot can monitor market conditions in real-time, such as pool burn, mint renounced and other factors, and it will execute trades when these conditions are fulfilled.

 - `MAX_SELL_RETRIES` - Maximum number of retries for selling a token.
 - `AUTO_SELL_DELAY` -  Delay in milliseconds before auto-selling a token.
 - `PRICE_CHECK_INTERVAL` - Interval in milliseconds for checking the take profit and stop loss conditions.
+  - Set to zero to disable take profit and stop loss.
 - `PRICE_CHECK_DURATION` - Time in milliseconds to wait for stop loss/take profit conditions.
   - If you don't reach profit or loss bot will auto sell after this time.

+- `CONSECUTIVE_FILTER_MATCHES` - How many times in a row pool needs to match the filters.

 - `USE_SNIPE_LIST` - Set to `true` to enable buying only tokens listed in `snipe-list.txt`.
