But I argue from a point of vantage. Is there any time when the cards are stack in your favour ?
Of course.
You are not martingaling the EV, ( which is absolutely independent) .. it’s the prevailing conditions , in short trading what you see , something like order flow.. top range, resistance . Support, vwap , correlation etc.
When the conditions are right , the odds are in your favour but that doesn’t change the expected value of any price movement outcome .
As you say given time , everything that must happen will happen. Now let’s assume that the fill rate is 100% , liquidity 100% backers and layers at equal amounts , this will still not stop prices stalling and overshooting at crossover points. FOMO and STOP loss hunts, will ensure that price movement is biased towards one way or another and also the pay offs are well structured to favour the layer than the backer .
Now if you took red on roulette table and I took black , the only winner is the house/ exchange.. due to commission/ house edge .. but if one of us took a strategically advantageous position at a crossover point ..things change . But the expected values remain the same.
Hope that makes sense.

But there are bell curves/ EV/ p values/ house edges.
And you don’t have to worry about fill rate where
Your martingaled orders won’t be filled.
