Quote from jack hershey:
You have an edge when your trading approach doesn't use probability. That is, you have recognized probability is not a requirement in trading.
Another symptom is not using entry/exit approach. The alternative is hold/reverse.
Quote from killthesunshine:
i have a better question:
What is a clue that your strategy is really no edge at all but just vicissitudinary chance?
Quote from ElectricSavant:
vi·cis·si·tu·di·nar·y (v-ss-tdn-r, -tyd-) also vi·cis·si·tu·di·nous (-tdn-s, -tyd-)
adj.
Characterized by, full of, or subject to vicissitudes
Quote from killthesunshine:
pure chance events like coin flipping can have long runs in one direction or another ...which might fool you into thinking you have an edge when you do not.
how quickly can you know that your trading is no better than a coin flip?
do you have more to add than a definition?
