I've used Trading Central's free signals in the past and found them generally reliable, particularly for forex and major indices. However, like any tool, they should be part of a broader strategy rather than relied upon solely. It's essential to compare their signals with your analysis and other sources to make well-informed decisions. Many traders find value in their technical analysis component, but individual results can vary. Always consider back-testing signals on historical trades to see how they align with your trading goals.
