# Why can't I specify less than 1% for ''Buy'' and ''Sell'' in the grid settings?

You can set a grid percentage value **from 0.5%** <mark style="color:purple;">**for buying**</mark> on all exchanges supported by the bot.&#x20;

However, <mark style="color:$danger;">**it is not possible to set a sell percentage below 1% on exchanges**</mark> (except Binance), because at values below this threshold, the bot would operate at a loss due to fees (both its own and the exchange's). Thus, the minimum sell percentage is set to account for the amount of commission fees, ensuring the bot can execute profitable trade
