A system consists of (a) a set of rules that you use to select profitable positions and (b) a set of rules that you use to manage the trade once you're in it (whether you call it a system, a method, a strategy, a plan, a scheme, an approach, a procedure, or a modus operandi is not as important as sitting down and doing it). You've made a start with "a 25% price increase with high volume low float and two green 5 minute bars over the vwap and moving averages," but now you have to test it and keep detailed records of each trade, successes and failures, including simple statistical summaries of what you did and the results. Using "replay" will enable you to collect the data much faster.
The following is an illustration of "the scientific method". You'll get to know it very well.
