dYdX strategy design paradigm - Randomized trading strategy

dYdX policy design paradigm

In response to a lot of users' needs, recently FMZ platform supported the dYdX decentralized exchange. Small partners with strategies can enjoy mining dYdX. Just a long time ago, I wanted to write a random trading strategy, making money and losing money without any apparent purpose is to practice hand-in-hand teaching a little strategy design.

The first wave of mining.

This is a screenshot of the mining strategy in this post.

Randomized trading strategy design

Let's try to think it over! We plan to design a strategy that does not look at the indicator, does not look at the price randomly ordered, the only option is to do more, do nothing, what is blocked is probability. Then we use random numbers 1 to 100 to determine how much space.

Multiple conditions: random number from 1 to 50. To do the empty condition: random number 51 to 100.

The number of spaces is 50 numbers. Next, we will think about how to equalize, since it is a draw, then there must be a win-win standard. Then in trading, we will set a fixed stop loss as a win-win standard. Stop loss is a win, stop loss is a loss.

It's not cost-free, there are slippage points, fees, and other factors that are enough to push our winning odds of random trades to less than 50%. It's better to design a multiple bet, since since it's a jackpot, the probability of losing 10 consecutive 8 random trades shouldn't be very high. So I wanted to design the first trade with a small amount, and then increase the next amount if the jackpot loses.

OK, the strategy is simple enough to design.

Design source code:

var openPrice = 0 
var ratio = 1
var totalEq = null 
var nowEq = null 

function cancelAll() {
    while (1) {
        var orders = _C(exchange.GetOrders)
        if (orders.length == 0) {
            break
        }
        for (var i = 0 ; i < orders.length ; i++) {
            exchange.CancelOrder(orders[i].Id, orders[i])
            Sleep(500)
        }
        Sleep(500)
    }
}

function main() {
    if (isReset) {
        _G(null)
        LogReset(1)

I've done the retesting, no bugs. But I feel like I'm in the right system for the retesting...T_T, the real disk is running and playing.
