ETHUSD lot size calculator

On ETHUSD a lot is 1 ether at Capital.com, so a $1 move is $1 per lot. Risking 1% of $10,000 with a $75 stop gives 1.333 ETH, rounded down to 1.33 lots.

The calculator opens on the worked example below: a USD account, 1% of $10,000. Trading involves substantial risk of loss and is not suitable for every investor.

What 1 point is on ETHUSD

An ETHUSD CFD is priced in dollars per ether. Capital.com publishes a contract size of 1, so profit = dollars moved × lots and a lot size is a number of coins. Other brokers may use another contract size: the Specification window is the reference.

At around $3,500, ether moves fewer dollars than bitcoin, so stops are tens of dollars rather than thousands, and lot sizes are larger. On a 2-digit quote the MT5 point is $0.01: a $75 stop is 7,500 points.

ETHUSD point value per lot

Value of one point (1.00 in price): 1 × 1 = $1 per 1.00 lot, with a contract size of 1.

Position1 point75 points (75.00)
1.00 lot$1.00$75.00
0.10 lot$0.10$7.50
0.01 lot$0.0100$0.75

Worked example: 1% of $10,000

  1. Risk: 1% × $10,000 = $100.00.
  2. Stop: 75 points = 75.00 in price.
  3. Value of 1 point per 1.00 lot: $1.00.
  4. Lot size = $100.00 ÷ (75 × $1.00) = 1.3333, rounded down to the 0.01 step: 1.33 lots.

The exact size is 1.3333 ETH; rounded down to 1.33 the loss at the stop is $99.75.

Contract size and tick value in MT5

In MetaTrader 5, right-click ETHUSD in Market Watch and choose Specification: it shows Contract size, Digits, Profit currency and the volume limits. Tick size and tick value are what MQL5 reads with SYMBOL_TRADE_TICK_SIZE and SYMBOL_TRADE_TICK_VALUE; the script below prints them for your account.

MQL5: lot size from a money risk

A script that sends no order: it reads the contract size, tick size, tick value and volume limits your broker sets for ETHUSD, then prints the lot size that risks 1% of the balance at the stop. The stop is a price distance (75.00), so the result is the same on 2-, 3- or 5-digit quotes. Save it as MQL5/Scripts/LotSize_ETHUSD.mq5 and compile it in MetaEditor (F7): 0 errors, 0 warnings.

      PrintFormat("Lot size: %g", lots);
   else
      Print("Even the minimum volume risks more than that: widen the risk or tighten the stop");
  }

The key line is stopDistance / tickSize * tickValue: the money one lot loses at the stop, already converted to your account currency by the terminal. Dividing the risk by it and flooring to SYMBOL_VOLUME_STEP gives the volume to pass to CTrade::Buy() or CTrade::Sell().

Pine Script v6 equivalent

The same sizing on a TradingView chart, from syminfo.pointvalue (money per 1.0 of price per unit) and syminfo.mintick (the chart's tick). Checked by Edgoro Pine Check; paste it into TradingView's Pine Editor to add it to a chart.

Pine Script v6
//@version=6
indicator("ETHUSD lot size for a money risk", overlay = true)

riskMoney    = input.float(100.0, "Risk per trade (account currency)", minval = 0.01)
accountCcy   = input.string("USD", "Account currency")
stopDistance = input.float(75.00, "Stop-loss distance (price)", minval = 0.0)
contractSize = input.float(1.0, "Units per 1.00 lot at your broker", minval = 0.0)

// One unit of the symbol gains or loses syminfo.pointvalue (in syminfo.currency) per 1.0 of price
fx          = request.currency_rate(syminfo.currency, accountCcy)
lossPerUnit = stopDistance * syminfo.pointvalue * fx
units       = lossPerUnit > 0 ? riskMoney / lossPerUnit : na
lots        = contractSize > 0 ? math.floor(units / contractSize * 100) / 100 : na

var table info = table.new(position.top_right, 2, 3, bgcolor = color.new(color.gray, 80))
if barstate.islast
    table.cell(info, 0, 0, "Stop")
    table.cell(info, 1, 0, str.tostring(stopDistance / syminfo.mintick, "#") + " ticks of " + str.tostring(syminfo.mintick))
    table.cell(info, 0, 1, "Units")
    table.cell(info, 1, 1, str.tostring(units, "#.####"))
    table.cell(info, 0, 2, "Lots (rounded down)")
    table.cell(info, 1, 2, str.tostring(lots, "#.##"))

On a CFD chart syminfo.pointvalue is usually 1, so units is the number of coins: set the contract size input to your broker's value. On a futures chart, syminfo.pointvalue already includes the contract multiplier, so units are contracts and the contract size input should be 1.

Common mistakes on ETHUSD

  • Bitcoin habits. A 0.06-lot size from BTCUSD on ETHUSD with a $75 stop risks $4.50: recompute for every symbol.
  • MT5 points. "75 points" on a 2-digit quote is $0.75.
  • Another contract size. If your broker's Contract size isn't 1, multiply the value per lot accordingly.

Lot size sets how much a trade loses if the stop is hit at its price. It doesn't make a trade a good one, and gaps or slippage can make the loss larger. Trading involves substantial risk of loss and is not suitable for every investor.
