Ask most active flippers how much they've made this week and you'll usually get a guess, not a number. Memory is a poor bookkeeper — it remembers the big wins vividly and quietly forgets the small losses. A portfolio isn't just a nice-to-have feature; it's the only way to actually know how you're doing.

What's worth tracking

At minimum: what you paid, how many units, and what it's worth right now at current market prices, net of the sell tax you'd pay if you cashed out today. That gives you both a realized picture (flips you've completed) and an unrealized one (positions you're still holding), which are genuinely different things — a holding that's currently up on paper hasn't actually made you anything until you sell it.

The behavioral benefit is bigger than the accounting benefit

There's a well-known tendency to hold onto a losing position hoping it recovers, rather than admitting the flip didn't work and moving on — sometimes called the sunk cost fallacy. It's much easier to fall into when the loss only exists in your head. Seeing a position clearly marked in red, with a real number attached, makes it noticeably easier to cut a bad flip instead of quietly holding it for weeks hoping to break even.

A portfolio that only feels good to look at when you're winning isn't giving you an honest picture. The real value is in seeing the losers as clearly as the winners — that's what actually improves your decisions over time.

Spotting your own patterns

Over enough flips, a tracked history starts to reveal things memory alone won't — which categories of items you're consistently good at reading, and which ones you think you understand but actually lose money on more often than not. That's genuinely useful information for deciding where to focus your capital and attention going forward, and it's essentially invisible without a record to look back on.

Realized versus unrealized is worth separating clearly

It's tempting to look at your total portfolio value and treat the whole number as "profit," but an unrealized gain on a position you're still holding can vanish before you ever sell — prices move, and paper gains aren't locked in until you actually close the position. Keeping realized profit (flips you've actually completed and cashed out) mentally separate from unrealized value (what your current holdings are worth right now) gives you a much more honest sense of what you've actually banked versus what's still at risk in the market.

A record protects you from your own optimism

Most people are naturally optimistic about their own trading decisions in the moment — nobody buys expecting to lose. A written record doesn't share that optimism; it just shows what actually happened. Reviewing a tracked history after the fact, once the emotional pull of "I really think this one will come back" has faded, tends to produce much clearer, more honest conclusions about which decisions were genuinely good and which just felt good to make at the time.

How often to actually check it

Checking your portfolio constantly throughout the day can be counterproductive — short-term price wiggles on a position you're planning to hold for a while can trigger anxiety-driven decisions that a longer view wouldn't. A daily or twice-daily check is usually enough to stay informed and catch anything that genuinely needs attention, without falling into the trap of reacting to every small, meaningless fluctuation as if it were a signal to act.

Setting exit rules before you buy, not after

One of the most useful things a portfolio view enables is deciding your exit point — both the profit target and the point at which you'll cut a loss — before you're emotionally invested in the outcome, rather than improvising once the position is already moving against you. Writing down (even just to yourself) "I'll sell if this drops below X" at the moment you buy is a very different mental exercise than deciding it while watching the position bleed in real time. A portfolio that shows your original buy price clearly next to the current price makes it much easier to actually stick to a rule you set for yourself in a calmer moment.

None of this needs to be complicated. Even a simple habit of glancing at your positions once a day and asking "does this still match my original plan for it" catches most of the value a full tracking habit provides, without turning portfolio review into its own time-consuming chore.

The tracker's Portfolio tab tracks every holding against live prices automatically, net of the current sell tax, so your unrealized profit and loss is always accurate to the current market — not a stale snapshot from whenever you last did the math by hand.
