Perpetual futures on a shilling budget: sizing a position so one bad candle doesn't end the account

When your trading budget is a few thousand shillings, a normal-sized position feels pointless, so the leverage slider starts looking attractive. That is exactly how many small accounts in Kenya are wiped out in a single sharp candle. The fix is not a magic leverage number but a different order of thinking: decide what one trade may cost you in shillings, place the stop where the trade idea is proven wrong, and let those two numbers set the size. Leverage then only decides how much margin you lock up.

Decide the shilling amount one trade may cost

Pick a fixed share of your trading budget that you accept losing on a single trade, small enough that a run of losses does not end your account. Write it in shillings and in USDT at today's rate. This number matters more than anything on the chart, because it stops one bad decision from becoming the last one. If the money in the futures account is money you need for rent, school fees or M-Pesa float, it should not be there at all.

Let the stop distance set the position size

Look at the chart and decide where your idea is clearly wrong; that is your stop. Measure the distance from entry to stop. Divide your allowed loss in USDT by that distance and you get the position size. A wide stop means a small position, a tight stop allows a larger one. Only now open the order form, choose isolated margin and set leverage just high enough that the margin required fits in your account. The order form on each exchange shows the margin cost and an estimated liquidation price.

Check liquidation, fees and funding before confirming

Make sure the estimated liquidation price is well beyond your stop, otherwise liquidation can arrive first. Fees are charged on the full position value, not on your margin, so on small accounts they take a noticeable bite; your rate is listed on the exchange's fee page. If you will hold through a funding time, read the current funding rate and countdown at the top of the contract page and include it in your expected cost.

Keep a short log and review it weekly

After every trade, write the date, pair, size, stop, result and fees. Once a week, read the log. Are you moving stops, increasing size after losses or trading out of boredom? Those patterns hurt small accounts faster than any market. If your losses exceed what you planned, pause and practise with the smallest possible size, or with a demo mode where the exchange offers one, before adding more shillings.

Scenario checkpoint

• Write down the maximum loss per trade in shillings and USDT before you look at leverage.
• Calculate position size from the stop distance and set leverage only to fit the margin.
• Confirm the estimated liquidation price sits well beyond your stop and include fees and funding.
• Log every trade and review the log weekly for moved stops or oversized positions.
