Privacy & Trust First

"Understanding your true 'average cost' is critical for trading psychology. Many beginners only track their buy price, ignoring exchange fees (0.1% - 1.5%), which raises their actual break-even point. This tool factors in those hidden costs, ensuring you don't exit a trade prematurely thinking you are in profit when you are actually just covering fees."
