A small team building the tools we wanted at our own desks
We are TachiTeam, a group of forex and gold traders and MetaTrader developers based in Vietnam. TachiTrade is where we publish free calculators for position size, risk and prop firm rules, and where we show the indicators and utilities we sell on MQL5.
Three things, kept separate
Calculators are free and stand on their own. Our MQL5 products are paid and clearly labelled. Nothing is hidden behind the other.
Free trading calculators
Lot size, pip value, margin, risk to reward, drawdown recovery, risk of ruin and more. Each one shows its formula so you can check the maths yourself.
Browse all calculators →Prop firm and gold tools
Daily loss and drawdown limits, challenge pace, and gold contract maths. Independent of any firm, and we say which rules we checked.
See the prop firm tools →MetaTrader indicators and utilities
Our own products on the MQL5 Market. Each listing states what it does and what it does not do. They are tools, not signals.

Show the maths
Formulas and assumptions sit next to every result. If you disagree with a step, you can see exactly where.
Say the limits
Every tool lists what it cannot do. A calculator is only as good as the numbers you enter.
Check with your broker
Contract size, margin and swap differ between brokers and accounts. Treat our figures as a second opinion, not the final word.
No signals, no promises
We do not sell signals, copy trading or guaranteed results. Trading carries a risk of loss.

How this site earns money
TachiTrade is free to use. These are the ways it is funded, so you can judge our advice with the full picture.
Details are on our Affiliate Disclosure page. If we add advertising or other income later, we will say so there.
