What 1 pip is on CADJPY
CAD/JPY is quoted in yen per Canadian dollar and trades around 108.7 (USD/JPY 150 ÷ USD/CAD 1.38). The pip is the second decimal, so a lot is worth ¥1,000 per pip.
The conversion to dollars goes through USD/JPY, never through the Canadian dollar: ¥1,000 ÷ 150 = $6.67. MT5 quotes 3 digits, so the 0.001 tick is worth ¥100 per lot.
CADJPY pip value per lot
Value of one pip (0.01 in price): 0.01 × 100,000 = ¥1,000 ÷ 150 = $6.67 per 1.00 lot, at an example USD/JPY rate of 150.
| Position | 1 pip | 30 pips (0.30) |
|---|---|---|
| 1.00 lot | $6.67 | $200.00 |
| 0.10 lot | $0.67 | $20.00 |
| 0.01 lot | $0.0667 | $2.00 |
Worked example: 1% of $10,000
- Risk: 1% × $10,000 = $100.00.
- Stop: 30 pips = 0.30 in price.
- Value of 1 pip per 1.00 lot: $6.67.
- Lot size = $100.00 ÷ (30 × $6.67) = 0.5000, rounded down to the 0.01 step: 0.50 lots.
The same stop and risk as the USD/JPY example give the same size: the pip value of both pairs is ¥1,000 per lot.
Contract size and tick value in MT5
In MetaTrader 5, right-click CADJPY 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.
| Contract size | 100,000 CAD |
|---|---|
| Digits | 3 (e.g. 150.125) at most brokers |
| Tick size (SYMBOL_TRADE_TICK_SIZE) | 0.001 |
| 1 pip | 0.01 = 10 ticks (10 MT5 points) |
| Profit currency | JPY |
| Tick value, 1.00 lot (SYMBOL_TRADE_TICK_VALUE) | ¥100, about $0.67 in a USD account at USD/JPY 150 |
| Volume step | Shown in Specification; 0.01 at most retail brokers |
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 CADJPY, then prints the lot size that risks 1% of the balance at the stop. The stop is a price distance (0.30), so the result is the same on 2-, 3- or 5-digit quotes. Save it as MQL5/Scripts/LotSize_CADJPY.mq5 and compile it in MetaEditor (F7): 0 errors, 0 warnings.

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.
//@version=6
indicator("CADJPY 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(0.30, "Stop-loss distance (price)", minval = 0.0)
contractSize = input.float(100000.0, "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

On a TradingView forex chart, syminfo.pointvalue is 1: units is an amount of CAD, and 100,000 of them make a lot. request.currency_rate() converts the JPY result into your account currency.
Common mistakes on CADJPY
- Converting through CAD. The profit is in yen; USD/CAD plays no part in converting it.
- Thinner liquidity. CAD/JPY is traded less than the majors, and its spread can widen in quiet hours: add the spread to the stop you size for.
- Decimal places. 30 pips are 0.30 in price and 300 MT5 points.
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.
