What is on this screen
- A Lot calculator tab for finding the lot size that fits your risk
- A Swap tab for calculating swap costs by the number of nights held
- An R: R tab for calculating the risk-reward ratio and the minimum Win Rate
- A Gold tab for converting gold weight and calculating its value

Calculator 1: Lot
- Input fields are the pair, balance (USD), leverage, risk %, stop loss (Pips)
- Results are the LOT size, amount at risk, TP 1:2 profit, Pip value, Margin, profit/loss
- Leverage options are 1:50 1:100 1:200 1:500 1:1000
- Risk options are 0.5 1 2 3 percent, plus a custom setting
- Example: pair XAUUSD, balance 1,000 USD, leverage 1:500, risk 1%, stop loss 50 Pips — the result is a LOT size of about 0.20

Calculator 2: Swap
- Input fields are direction (BUY Long or SELL Short), Lot, number of nights
- Results are the Swap value, per night, Wednesday (3x), total
- Wednesdays count triple, as is normal in the market
- Example: direction BUY Long, Lot 0.10, 3 nights — the result is a total swap of about 2.40 USD
Calculator 3: R:R
- Input fields are entry price (Entry), Take Profit (TP), Stop Loss (SL), direction
- Results are Risk: Reward, minimum Win Rate, rating (excellent, good, low)
- The minimum Win Rate is the lowest win rate at which a trading system breaks even, computed from the risk-reward ratio
- Example: entry 2000, TP 2060, SL 1980 — the result is Risk : Reward 1:3 and a minimum Win Rate of 25%
Calculator 4: Gold
- Input fields are quantity, baht of gold
- Results are grams, ounces, value
- 1 baht of gold = 15.244 grams, and 1 ounce = 31.1035 grams
- Example: quantity 1 baht of gold — the result is 15.244 grams or 0.49 ounces
