#### exchangeInfo(): Pull minimum order size, quantity, etc.

```js

//minQty = minimum order quantity

//minNotional = minimum order value (price * quantity)

binance.exchangeInfo(function(error, data) {

let minimums = {};

for ( let obj of data.symbols ) {

let filters = {status: obj.status};

for ( let filter of obj.filters ) {

if ( filter.filterType == "MIN_NOTIONAL" ) {

filters.minNotional = filter.minNotional;

} else if ( filter.filterType == "PRICE_FILTER" ) {

filters.minPrice = filter.minPrice;

filters.maxPrice = filter.maxPrice;

filters.tickSize = filter.tickSize;

} else if ( filter.filterType == "LOT_SIZE" ) {

filters.stepSize = filter.stepSize;

filters.minQty = filter.minQty;

filters.maxQty = filter.maxQty;

}

}

//filters.baseAssetPrecision = obj.baseAssetPrecision;

//filters.quoteAssetPrecision = obj.quoteAssetPrecision;

filters.orderTypes = obj.orderTypes;

filters.icebergAllowed = obj.icebergAllowed;

minimums[obj.symbol] = filters;

}

console.log(minimums);

global.filters = minimums;

//fs.writeFile("minimums.json", JSON.stringify(minimums, null, 4), function(err){});

});
