In the context of technical analysis, it is the process of adjusting one's trading system in an attempt to make it more effective. These adjustments include changing the number of periods used in moving averages, changing the number of indicators used, or simply taking away what doesn't work.
Investopedia Says:
For example, if an investor has a simple trading system that is just composed of a crossover of closing price and a moving average, by changing the periods of the moving average, the trader will get different profits, risk, capital drawdowns, etc. Thus, optimization helps you to choose the optimal parameters to trade.
