A lot is just a fixed contract size — a standard way of describing how much of something you're trading, so a "1.0" position means the same thing to every trader using it. On gold, that standard size has a very specific, easy-to-forget number behind it.
The actual number
A standard lot of gold (XAU/USD) is 100 troy ounces. Not 100 tola, not 100 grams — 100 troy ounces specifically, the international unit gold trading is priced in.
Most retail traders never trade a full standard lot — it's a large position. Brokers typically offer fractional sizes: a mini lot (0.10, or 10 troy ounces) and a micro lot (0.01, or 1 troy ounce) are the sizes most beginners actually use.
What this means in tola terms
Since one troy ounce is roughly 0.375 tola, a full standard lot of gold (100 troy ounces) works out to roughly 37.5 tola — a genuinely large amount of gold to be controlling in a single position, even though the margin required to open it is only a fraction of its full value, because of leverage.
A micro lot (1 troy ounce) is closer to 0.375 tola — small in physical-gold terms, but often still a meaningful position size on a modest trading account once leverage is factored in.
Why lot size is the real risk lever
The size of the lot you trade — far more than which direction you guessed, or which signal you followed — determines how much a given price move actually costs or earns you. Two traders can take the identical SonaPips Gold signal, agree on entry and stop loss, and end up with completely different real outcomes purely because one used a 0.10 lot and the other used a 0.50 lot.
This is why position sizing always has to come before entry — deciding lot size based on your actual risk tolerance in PKR, not picking a size that "feels right" or matches what someone else is trading.
A worked example
Say you're comfortable risking PKR 2,800 (about $10 at 280 PKR/USD) on a trade, and your stop loss sits $2 away from your entry. On a micro lot (0.01, or 1 troy ounce), a $2 move costs $2 — well within your $10 risk budget, with room to spare. On a mini lot (0.10), that same $2 move costs $20 — already double your intended risk. The lot size, not the trade idea, is what determines whether this fits your actual risk tolerance.
The honest part
Lot size isn't a technical detail to skim past — it's the single number that translates a price move into real money, more directly than almost anything else in a trade. Getting comfortable with what 0.01, 0.10, and 1.0 actually represent in gold specifically (not forex pairs generally) is worth the few minutes it takes.
SonaPips doesn't tell you what lot size to trade — that depends on your own account and risk tolerance — but every signal on Gold, EUR/USD, and GBP/USD includes the real entry, stop loss, and target prices needed to work that number out for yourself, honestly, before you enter.
