Failure of the Coiled spring strategy or lack of testing

It has been a losing streak for quite a long number of days now. After trying out Price action sanuk and Buff trading, I was trying out Coiled spring trading. Needless to say, it performed worse than the other too. Well on a macro retrospection, I came to the conclusion that out of the three strategies, coiled spring gave the maximum returns. Maybe I could not milk the strategy due to lack of Optimisation and Testing of the trading system. So this is the plan. I am going to run all possible tests, optimizations, walk-forward tests to see how the trading system performs. It might take a week to do the same. I would be refraining from realtime trading during this testing.
