I don't think being confident is an edge. It may lead to having an edge but it by itself is not an edge. For example, I can be very confident that I can beat the heck out of Mike Tyson in a fist fight. But confidence can be just hallucination not reality. If your systems/methods can lead to >50% winning over the long haul, then you can be confident of your systems/methods.
If you are losing/not making money, look into the mirror and ask yourself how you are doing with these 3Ms. Thank you Detrader9.
What is an edge? It is STATISTICAL evidence that serves as VALIDATION or CONFIRMATION to REPEAT what is basically the SAME trade AGAIN and AGAIN. You ask politely do I have an edge? As no one less than Dick Martin said many times, you bet your sweet BIPPY I do.
MM style situation It can be in an indervidual, although rarely, as generally their behavior/insight can't be replicated. Everything else is a competative advantage at best with the caveat that very few people do in fact have this advantage! Regards Johno
When a response likes yours barely has a passing relation to the post, it is not really worth addressing.
None of these are edges and you don't know what you're talking about. These are generic & basic aspects of trading. A true edge is a trick or methodology that has a very favorable risk/reward ratio. Some edges are near risk free, like certain arbs of ECNs or ATS versus the NYSE back before NYSE Hybrid. It simply required thinking ahead outside the box and setting up the proper resources to take advantage of these opportunities.
