A real edge hardly requires any testing

    You could get lucky and think you are a trading genius when you have just been lucky in your trades. I found what I thought was a trading system that was very good and had an edge. On paper (with a limited data of about 205 trades) seemed that would be close to a sure thing. Now, comes the actual test with real monies on the line and it fails terribly. Did not count on the huge slippage involved since, I trade options as a buyer. I took the lumps on the losing trades as I had proper risk management. Anybody can get lucky trading the stockmarket. You probably, need atleast, 500 actual real life trades to validate you even have something with an edge.

    Some say tick charts and big candles are edge enough. The real edge is logic shouldn't be clouded by taking on too much risk.

    Edge must be quantifiable, exploitable, and scalable.

    How much edge exists? Can you capture that edge? Does that edge persist when increasing bet size?

    The classic thread of illusory epiphanies™ after a few profitable months. We've all been there but your current state of clarity won't last.

    This post reeks of nativity. Over course you have been only trading for five months. Come back and read this post after you’ve been trading for 20 years.

  8. To be fair, I said “not much doubt”, but let’s say you thought you had a high chance of -2% and a low chance of +2% depending on what happens across earnings or similar. On one hand, it’ll be hard to get enough data to be sure the odds really are say 4:1 in your favor or whatever, but on the other hand, if you keep putting on the bearish trades and more than 2 go against you before you’re making money, you know something’s probably wrong with your model.

    Right. I have been doing this for my sole source of income for over a decade. It is definitely my lack of understanding that is the problem.

    Thats the thought, which is not necessarily right, I feel. Let me rephrase myself, if and when you find a real edge, you will know it, thats what I meant.

    If the edge is not good enough, you will have to go for testing it out.

    But,
    An edge should stand by itself, testing on data sets give you an edge on those data sets only.
