Why use custom JS strategies
Gunbot comes packed with hundreds of configurable strategy options. These options can be used for great trading strategies, but not every imaginable scenario can be handled with preset options. Custom strategies give you full freedom. For example a preset strategy option might give the option to trigger an order when RSI is above or below X, with a custom strategy you could additionally do a lookback of x periods, or calculate the slope RSI is drawing. By default Gunbot calculates about 20 different indicators for its built in strategies. But of course there are many more indicators out there. In a custom strategy you can use exactly the indicators you need, and often NPM will have a ready made module for it. Want to use alternative data sources next to data coming from the exchange directly? Now you can.
// collect indicator data
let rsi10
let rsi20
gb.method.tulind.indicators.rsi.indicator([gb.data.candlesClose], [10], function (err, results) {
rsi10 = results[0]
});
gb.method.tulind.indicators.rsi.indicator([gb.data.candlesClose], [20], function (err, results) {
rsi20 = results[0]
});
// define trading conditions
const entryConditions = (
rsi10[rsi10.length - 1] > rsi20[rsi20.length - 1] &&
rsi10[rsi10.length - 2] < rsi20[rsi20.length - 2]
)
const exitConditions = (
gb.data.gotBag &&
rsi10[rsi10.length - 1] < rsi20[rsi20.length - 1] &&
rsi10[rsi10.length - 2] > rsi20[rsi20.length - 2]
)
// place orders when trading conditions happen
const buyAmount = parseFloat(gb.data.pairLedger.whatstrat.TRADING_LIMIT) / gb.data.bid
if (entryConditions) {
gb.method.buyMarket(buyAmount, gb.data.pairName)
}
else if (exitConditions) {
gb.method.sellMarket(gb.data.quoteBalance, gb.data.pairName)
}
Dual RSI strat
This example shows how you can create a simple trading strategy. The strategy places a market buy order when a 10 period RSI crosses over a 20 period RSI, and places a market sell order on the crossdown. First you would generate your RSI data, once for a 10 period and once for a 20 period RSI. This is done using the tulind library, but you could use any method you want. Often you could use pre calculated indicator values, but in this case we need the full array to detect crosses. Then the crossing conditions are defined, when these happen an order gets sent.
Can I code xyz in Gunbot?
