What Restrike does, what it won't do, and what happens to what you type into it.
It tracks the option strategies you run. Log trades by hand or import them read-only from your broker (Restrike never places a trade), and it folds rolls and spreads into single positions and scores each strategy on its own: P/L, win rate, and how it's doing against the rule you set.
It also sizes one strategy, the at-the-money put overlay, because that one has a backtest behind it. It doesn't recommend a position or forecast a return.
No. It follows positions held for weeks or months: overlays on a portfolio, covered calls and the wheel, hedges, and swing trades.
It gets no options chain and no prices during the day, computes no Greeks, and grades a position only once it's closed, so nothing in it moves fast enough to trade on. What it's built for.
No, and it never will, on any plan. Brokerage import is read-only: it reads what you hold so you don't have to type it, and that's all it can do in your account.
Placing trades is the line that would make this a regulated advisory product, so Restrike stays on the other side of it.
No. Restrike is a tracker and a calculator, and its author is not a registered investment adviser. Nothing here is a recommendation, and nothing is personalised to you.
Sizes are labelled by consequence: whether a size came through the worst month in the sample. The tool never calls a size "safe".
No. The tracker works signed out, and while you're signed out nothing you type leaves your browser.
Signing in syncs your log and holdings across your devices and starts 30 days of Pro, with no card. That's the point where your data reaches us, and the privacy page lists exactly what.
Tracking is free, with nothing held back: every strategy, unlimited trades, and sync across your devices.
Pro is for what has to happen without you remembering: reading your broker (read-only; Restrike never places a trade) and the alerts. What each plan includes, and the price, are on the pricing page. Every new account starts with 30 days of Pro, no card.
On every plan, nothing reaches your log on its own: the importer proposes and waits for you.
From your billing page: open the menu by your email address and choose Manage subscription. It's Stripe's portal, so nothing waits on anyone here. Pro runs to the end of the period you've paid for.
Your log, holdings and settings stay. The brokerage connection is removed 14 days after Pro ends, with an email a week before, so a card that fails and gets fixed a few days later doesn't cost you a connection. You can disconnect it yourself at any time, subscribed or not.
No. Payment is handled entirely by Stripe on Stripe's own pages. No card number ever reaches this site, and none is stored here.
Signed out, nothing. Signed in, only what syncing needs, and no password, because you sign in by emailed link.
The itemised list is on the privacy page, and that list is the contract: nothing is stored that isn't on it.
Your positions, balances, past trades and recorded orders, read-only, through SnapTrade. Restrike never places a trade or moves money. You link your account on SnapTrade's own pages, so no brokerage password passes through this site. The privacy page says how that limit is enforced, and the brokers page lists which brokers connect.
An import never overwrites a table you typed. It shows you what came back and waits.
On Pro, at most brokers. Pressing Update reads your broker there and then, and opening the tracker reads it again once the last read is two hours old. Fidelity shares data once a day, so a position you closed there this morning shows until its next update.
Trades are slower: most brokers post them the next day, and three report the day's orders, which arrive the same day. The brokers page says which. The Portfolio says how old the figures are. On the free plan your broker isn't read.
Yourself, on Your account, from the menu by your email address. You can drop the synced copy and keep the account, or close the account entirely.
Closing can't be undone, so export anything you want first. What each option removes, including what SnapTrade is told to forget, is on the privacy page. What's in your own browser stays, because we can't reach it.
One strategy, a short put on the S&P 500 written at the money each month, has a thirty-year backtest behind it, and Restrike sizes it. These answers are about that strategy.
7,537 overlapping cycles of a monthly at-the-money short put on SPY from 1996 to 2026, closed at 50% of maximum profit and started on every day so no single entry date sets the result. The span includes 2008 and 2020.
Growth figures are total returns, dividends reinvested, so compare them with a total return rather than the share price. The method is on the research page.
Check it instead. Every page load re-prices twelve reference contracts and four margin cases against the backtest's own values, and the result is printed at the foot of the Sizing screen.
If that line is ever red, don't trust anything else on the page.
Around $20,000, because of granularity rather than a rule. Below that, one contract of the smallest S&P 500 instrument is more than 40% of the account, past the point where a repeat of the worst month on record ends the position.
You also need margin. Cash-secured, one contract ties up the whole strike; under Reg T it's about a fifth of that. Run your own number on the sizing screen.
Yes. The overlay's contracts are written on the S&P 500, and what you hold against them is yours to choose.
What changes is your beta. A book of single stocks usually moves more than the index, so your equity falls faster than what you're short and the cushion shrinks. Portfolio measures your blended beta, and the margin and shock figures run on it. A stock it has no beta for needs one typed in, and a stale one gives a confident, wrong cushion.
Because one index measured properly beats five guessed at. Every figure comes from one backtest on one index, and quoting its numbers beside a Nasdaq position would be a borrowed figure. This site has published one of those and corrected it in public.
The tool can also price one S&P 500 fund from another, because they move together. A fund on a different index can't be priced that way.
Because one contract size doesn't fit every account. One SPY contract is already too big for many six-figure portfolios, and SPYM is about an eighth of it. The sizing screen shows what one of each is worth against your equity.
Two are cash settled, so they can't be assigned, and the index contracts are taxed differently. Whether that's worth anything is a question for a tax professional.
Measured: at 25% notional, rolling into a new put the session the old one closes added 0.91 points of growth a year and 3.46 points of deeper worst fall. It traded about 2.0× as often, for a risk-adjusted return level with the monthly version.
Treat that growth as an upper bound: a real option chain doesn't always list a contract 30 days out. The study sets out both, including a cost figure this site once published wrongly.
Not the way most people expect. Splitting the same notional into rungs moved growth by 0.01 points and the deepest fall by 0.01 points: nothing.
What it changes is how much your result depended on the day you started. Two rungs removed 28% of that, six removed 76%, and past six it's flat. Rungs come out of whole contracts, so an account holding three contracts can make three rungs, not six.
That's a question about you, and this site knows nothing about you. What it can show is what each changed in 7,537 cycles of past data, with the drawdown beside every return, above and on the research page.
All three sell the same contract; only how often you open one changes. So only the growth and drawdown curves move with the setting.
Less than for someone who doesn't, and that's worth saying. A resting order closes the position with nobody watching.
The alert reads what you still hold, so a fill means silence. If an email does arrive, the mark is past your target and the contract is still yours: the order hasn't filled, which on a thin chain can go on for days. It's a check that what you set up is working.
Measured, and they don't add return. Monthly calls against shares you own, at four strike distances and four sizes over the same three decades: none of the sixteen beat holding the index, and the closer to the money, the wider the gap.
What they buy is a shallower fall, the opposite of the short put. Holding both was the best risk-adjusted result in the study, and the research page has the table.
The tool sizes and tracks them, scored on what the cap cost. It doesn't model tax: shares called away realise their gain that year, and that treatment needs somebody qualified before it goes in front of anyone.
