These add event-style spikes to the FX Vol concept. Average spike timing does not predict the timestamp of the next spike. Position size must start with the amount you can lose, followed by the stop distance in actual ticks and the symbol’s tick value converted to your account currency.
Step-by-step
- 1
Define the money you can lose
Choose an account balance and a small risk percentage. The calculator converts that percentage into a maximum money loss before lot size is considered.
- 2
Measure the stop distance
Decide where the trade is invalid before entering. Measure the distance from entry to stop using the price units shown by the instrument.
- 3
Read the live symbol specification
In MT5, open the symbol Specification and note Tick size, Tick value, minimum volume and volume step. Do not copy old values from screenshots or social posts.
- 4
Calculate the money risk per lot
Money risk per 1 lot = (stop distance ÷ tick size) × tick value. This converts the chart distance into account currency.
- 5
Calculate and round the lot size
Position size = money risk ÷ money risk per 1 lot. Round DOWN to the broker volume step, then make sure the result is not below minimum volume.
- 6
Recheck before sending the order
Confirm the symbol, stop price, volume and maximum loss. If the minimum lot would risk too much, skip the trade rather than forcing the size.
Position-size formula
Risk money = Balance × Risk %Money risk per 1 lot = (Stop distance ÷ Tick size) × Tick valueLots = Risk money ÷ Money risk per 1 lotAlways use the tick size and tick value shown for the exact symbol in MT5. Contract specifications can differ between Deriv, Weltrade, account types and instrument variants.
Common mistakes to avoid
- Using a standard forex “$10 per pip” rule for SFX Vol family may be badly wrong; a broker suffix, currency conversion or alternate contract changes the result.
- If the formula returns less than minimum permitted volume, do not force a position. Change the idea or stand aside.
- Do not assume a broker product is available in every country or that historical patterns guarantee results.
