Thanks for the reply. I am backtesting a system that uses Zig function. The backtest result is good, but I suspect Zig function may artificially increase the profit. I want to use Explore to generate signal day by day and compare with the backtest result, is this a good method to find whether the system is profitable? It is very time consuming to use Explore to generate signal day by day and than compute the result. Any quick method to test if the system is profitable in real trading? Thanks.

One additional use for Zig is to see if a security has large enough price swings to trade profitably. Some low volatility securities become unprofitable to trade if you factor in commissions and bid/ask slippage.
