Position trading describes a longer decision and review horizon, but there is no universal number of days that defines the style. State the intended holding window and decision cadence instead of relying on the label. A useful plan names the thesis, instrument, invalidation evidence, maximum exposure, carrying costs and date for the next review. “Long term” is not a risk control.
Separate the thesis from the trade mechanics
Describe the market hypothesis in a sentence and identify observations that would contradict it. Then choose an instrument that actually represents the question. Spot ownership and a perpetual contract have different financing, custody and counterparty considerations; a thesis about an asset does not automatically transfer to a margined derivative with funding, mark-price and liquidation rules.
Set an entry rule, sizing method, exit condition and maximum holding period. Define when you will review the thesis and which observations could change it. A scheduled review is not permission to move a stop simply because price is uncomfortable. Preserve revisions as new timestamped versions so a later explanation does not rewrite what was known at entry.
Keep similar price exposure in perspective
Consider a fictional 0.1 BTC position opened at $60,000. Its spot notional is $6,000. A linear perpetual position of the same size has similar first-order price exposure: a fall to $57,000 changes the price value by about −$300 before fees, funding or basis. The instruments still differ. The spot holder owns the asset subject to custody and venue risks; the perpetual account posts collateral, pays or receives funding under venue rules, and can be liquidated. Equal notional does not mean equal capital required or equal path risk.
Long holding windows accumulate changing assumptions
A perpetual held for weeks or months may cross many funding settlements; rates and even which side pays can change under the venue’s convention. Fees, collateral terms, mark-price rules and maintenance requirements can also vary with the market and account. For spot, custody, network and venue-access assumptions remain relevant. A backtest that omits these flows is testing a narrower question than the full holding process.
Model the intended holding window, include the historical cost records that actually exist, and mark missing intervals as unknown. Do not extend today’s funding quote across months as though it had been known in advance. Stress a gap, a funding reversal, wider spreads and a margin warning. For a venue-specific example, Hyperliquid’s margining and liquidation documentation explains that cross and isolated accounts use different collateral inputs, and its displayed liquidation estimate may change as funding, liquidity or other cross positions change. Other venues can use different rules.
A small funding ledger over a longer hold
Take the same fictional 0.1 BTC linear perpetual exposure at a constant $6,000 notional for four hourly settlements. Suppose the hypothetical funding rates are +0.01%, +0.02%, −0.005% and +0.03%. Hyperliquid documents hourly settlement and, for that venue, a positive rate means longs pay shorts while a negative rate reverses the payer. Under that stated convention, the simplified long’s net funding is $6,000 × (0.0001 + 0.0002 − 0.00005 + 0.0003) = $3.30 paid. If BTC also falls from $60,000 to $57,000, the simple price change is −$300 and the combined illustration is −$303.30 before trading fees, spread, basis, collateral effects or gaps.
This is an arithmetic sensitivity, not observed funding history or an estimate of future carry. It freezes notional for clarity; Hyperliquid’s actual funding payment uses position size, oracle price and the applicable rate at each settlement. The rate and direction can change, and another venue may use different timing or conventions. Four settlements cannot be annualized into a reliable long-horizon cost estimate. Use timestamped settlement records for the actual venue and leave missing observations unknown.
Plan the review before a drawdown
Write conditions that would lead to continuing observation, reducing a simulated position, stopping the study or gathering different evidence. If the thesis depends on a network, protocol or market assumption, record the source and a trigger for checking if it changes. A narrative that can explain every possible outcome after it happens cannot be fairly tested.
SuperQuant’s built-in backtests use hourly data with one position at a time and simplified margin and execution rules; bundled histories are synthetic. A long calendar span in generated candles is not evidence of years of real market regimes. CME Group’s general trade and risk-management guidance likewise frames position sizing around the account’s equity and the dollar distance between entry and stop; that futures guidance is not a crypto-specific trading result or a rule for every venue.
Before the next review, record one of four states: thesis intact under its written evidence, weakened while a named check remains due, invalidated under its stated condition, or unknown because evidence is missing. This prevents an open loss from becoming a new thesis after the fact; missing data is not confirmation. Use the trading plan template, read swing trading and funding rates, and compare the position-sizing method. Longer holding periods need explicit review and failure criteria; they do not establish lower risk. This guide is general education, not personal investment advice.
Review the thesis, the risk and the instrument separately
A calendar reminder helps only if it asks the same questions each time. Compare new evidence with the original thesis, then separately review instrument exposure, venue or protocol changes, collateral and any accrued carry. For a perpetual, reconcile actual funding settlements instead of multiplying today’s rate by the remaining calendar days. For spot, keep custody, access and concentration risks visible; spot avoids perpetual funding but does not remove market or venue risk.
Choose a review cadence that fits the evidence horizon and add event-triggered checks for facts that could invalidate the thesis. A slower review schedule does not reduce price risk. Record one outcome before acting: intact under the written evidence; weakened with a named check still due; invalidated under a predefined condition; or unknown because a source, venue rule or observation cannot be verified. “Unknown” is a research status, not a reason to quietly assume the thesis remains true.
Keep three decisions distinct: whether the thesis is still supported, whether the position’s planned exposure remains within its risk limit, and whether the instrument remains appropriate for the holding period. A thesis can remain plausible while the position must be reduced because exposure or margin changed. Conversely, a stable price does not repair evidence that has failed. Write the reason, source timestamp and next review date so a later reader can see what changed without rewriting the original plan.
