Position Size Drawdown Recovery Expectancy Tick & Pip Values Session Clocks
Tool 01
Position Size Calculator
Turn a risk rule into a real position. Pick your instrument, set the account, the risk per trade and your stop distance — Seris returns the size that keeps the loss inside your rule.
Position size

Enter your numbers to size the trade.
Risk amount—
Risk per unit—
Educational — not financial advice. Futures tick values are USD-denominated; if your account is in another currency, convert at your broker's rate. Always confirm contract specs with your broker before trading.
In the terminal, Seris sizes every trade for you →
Tool 02
Drawdown Recovery
The maths losses hide: a 50% drawdown needs a 100% gain to get back to even. Move the loss and watch how steeply the required recovery bends.
Read the lesson · Handling drawdown →
Gain needed to recover
100%
A 50% loss needs a 100% gain just to return to break-even.
Every $1,000 lost needs$1,000to rebuild
Educational — not financial advice. Recovery = loss ÷ (1 − loss). The curve is a mathematical identity, not a prediction of your account.
In the terminal, Seris watches your live drawdown & buffers →
Tool 03
Expectancy Calculator
What one trade is worth, on average, in R. Win rate and your average win / loss (in R multiples) decide whether an edge is positive — before position size ever enters the picture.
Expectancy per trade
+0.2R
A positive number means a mathematical edge over many trades — not a promise on any single one.
Over 100 trades+20R
Educational — not financial advice. Expectancy = (win% × avg win) − (loss% × avg loss), in R. Positive expectancy describes an edge across many trades; it never guarantees any outcome or profit.
In the terminal, Seris computes your real expectancy from your journal →
Tool 04
Tick & Pip Value Reference
Standard contract economics for the instruments traders reach for most — what one tick or pip is worth, and the contract behind it. Search or filter to find yours.
InstrumentClassTick / pipValueContract
Educational — not financial advice. Values are standard exchange contract specifications (USD); FX pip values are for one standard lot and JPY-pair values shift with the USD/JPY rate. Confirm specs with your broker.
In the terminal, presets fill your risk calculator automatically →
Tool 05
Session Clocks
Where the liquidity is right now. Live open / closed states for the four majors, with a countdown to each next open or close.
Educational — not financial advice. Times use standard session hours in UTC; local market equivalents shift with daylight-saving. A session being open is not a signal to trade.
In the terminal, session timers sit on your home dashboard →

The tools are free. The edge is yours to build.

Seris turns these one-off calculators into a terminal that knows your account, your journal and your rules.
