Well, to split hairs about semantics, "investments" and "expenses" are both spending, but one has a ROI in the form of utility or capital and the other doesn't. Everybody wants to reduce expenses, so why not lean towards policy that, in aggregate, produces more efficient spending? This would...

Survivorship bias. How much capital was wasted in aggregate by others investing in the competitors? Also, how much did your investment improve due to corporate tax cuts vs increased sales? No amount of cuts is useful without demand fueled by purchasing power.

Facetious or not, that is precisely what immigration is, no? Loosening immigration policy is something that the deflating and aging Japan has considered. As far as spending and investing, I think it concerns the most efficient use of capital. An investor can make bad investments and make...

Many popular against-the-grain theories are often wrong as well, I'm sure we could both cite research at each other endlessly. This one has some stats, but if you were to put it into your own words, what is your argument for it...

Just rehashing the apparently classic debate about whether consumption drives growth or production does. I mean, if they have to want it first, that's the demand, not the production first.

Someone mentioned that production drove demand, and not the other way around recently, and I swallowed it without really thinking about it at the time, only to learn in later reading that it is not a foregone conclusion and is really one of the bigger debates in modern economic theory. I don't...

Why not just go long 100 shares and collar it?

Not sure I understand; if a separate, competitive exchange came up that roadblocked HFTs, would they not get customers?

Exchanges like IEX have introduced their own perks that possibly draw people to them for equities, but how would competition be implemented for futures which all clear thru the same place right now?

Do you think a speedbump or other mechanical measure would be introduced to render such strategies useless?

If you can write your system down in concrete, non-subjective instructions, you can automate it.

What, you want me to pull out the calculator for him, too?

They will be repriced appropriately as the number of shares per option will be adjusted from 100 to 20.

Are you selling put spreads? Perhaps protect your downside with cheap long term puts? Essentially calendar spreading instead of pure put selling? Either way, you do have to consider volatility in your strategy. Sell long term when volatility spikes, etc.

Yes. I do that for the fixed volume bars.

I don't really wonder. I like to scale my charts by factors of 5. Wind up with some quirky intervals. To each their own.

Now, would you consider scaling in all one trade? Because you could also conceptualize each addition as a new trade. And does it make a difference? If I normally do 1 lot, and if I buy 2 lots and sell 2 lots, did I do the same trade twice or did I do one trade twice as big? Does scaling out...

Yeah, Ninjatrader lets you define the ticks in custom seconds, minutes, or days.

@algofy , If I were to speculate on @galvinlee888 's response, it's that he knows the math works, but implied that the conclusion drawn is insufficient for profitability, being based on several assumptions. 1. That any amount of consistency as stable as a winrate is possible, or meaningful...

Please explain how any of these charts are founded in logic, or backtesting.
