Liquidity is a key element in any successful trade, and many people might not pay attention to it, especially beginners. The first time I entered a currency with weak trading volume, I thought it was an opportunity because it was cheap, but when I tried to sell, I couldn't find buyers, and the price slipped against me significantly. Since then, I always check the trading volume and the depth of the order book before any entry. High liquidity means faster execution and a smaller price difference, while the opposite causes harmful price slippage even if I'm entering with a small amount. Now, I monitor pairs with high trading volume and avoid entering currencies that have low activity periods, especially during times of volatility. If I feel liquidity is weak, I use limit orders and don't rush into a market order because the price difference at that time can eat up all the profits or even turn the trade into a loss without justification. Liquidity is important, not just for execution but also for peace of mind while trading.
