A perpetual balance strategy suitable for bear market bottoming

In the past, FMZ officially released a perpetual grid strategy, which was popular among users, and the onlookers who traded TRX in real bots have gained a lot of profits in the past year with controllable risks. However, the perpetual grid strategy also has some problems:
1. It is necessary to set parameters such as initial price, grid spacing, grid value, long-short mode, etc. The settings are cumbersome and have a great impact on profits, making it difficult for novices to set.
2. The perpetual grid strategy has a high risk of short-selling, while the risk of long-selling is relatively low. Even if the grid value is set to a small value, it will not have a great impact on the short-selling price.
3. The perpetual contract grid can choose to only go long to avoid the risk of shorting, it seems okay so far. However, it needs to face the problem that the current price exceeds the initial price, resulting in a short position, and the initial price needs to be reset.

I wrote an article on the principle of the balance strategy and the comparison with the grid strategy before, and you can still refer to it now: https://www.fmz.com/digest-topic/9294. The balance strategy always holds positions with a fixed value ratio or value, sells some when it rises, and buys when it falls. It can be run with simple settings. Even if the currency price rises a lot, there is no risk of going short. The problem with the spot balance strategy is that the capital utilization is low, and there is no easy way to increase leverage. And perpetual contracts can solve the problem. If the total capital is 1000, 2000 can be held fixedly, which exceeds the original capital and improves the capital utilization. Another parameter is the adjustment ratio, which controls how much to sacle in or dump the position. If it is set to 0.01, it means that the position is dumped once for 1% increase and scaled in once for 1% decrease.

For beginners, the balance strategy is highly recommended. The operation is simple, just set a parameter of holding ratio or position value, and you can run it mindlessly without worrying about constant price increases. Those with certain experience can choose the grid strategy, and decide the upper and lower limits of fluctuations and the funds per grid, so as to improve the utilization of funds and obtain maximum profits.

By downloading the closing prices of all trading pairs from 2021 to the present, we can observe the changes in the overall market index: 2021 to 2022 is undoubtedly a bull market, and the index once rose by 14 times. It can be said that gold is everywhere, and many currencies have risen hundreds of times. However, in 2022, the bear market that has lasted for half a year has begun, with the index plunging 80%, and dozens of currencies have withdrawn by more than 90%. Such pump-and-dump reflects the enormous risk of grid strategies.
The index is currently at around 3, which is still a 200% gain compared to the beginning of 2021, and it should be a relative bottom at the moment, considering the development of the market.

First of all, we use the simplest code to simulate the situation of falling all the way down, and see the liquidation price of different position values. Since the strategy always holds a long position, there is no risk in going up. The initial capital is 1000, the currency price is 1, and the adjustment ratio is 0.01. The results are as follows. It can be seen that the risk of long liquidation is not low. With 1.5 times leverage, it can resist a 50% decline. Given the current relative bottom situation, it is an acceptable risk.

|Value of positions|Long position price|

First of all, we backtest the performance of the TRX balance strategy. The maximum retracement of TRX in this round of bear market is relatively small, so it has certain specificity. The data is selected from the 5min K-line from 2021 to the present, with an initial capital of 1000, the adjustment ratio is 0.01, the position value is 2000, and the handling fee is 0.0002.

The initial price of TRX was 0.02676U, and the highest price during the period reached 0.18U. It is currently around 0.08U, and the fluctuations are very violent. If you run the long-short grid strategy at the beginning, it is difficult to escape the result of short-selling. The balance strategies are less of a problem.

The final return of the backtest is 4524U, which is very close to the return of TRX at 0.18. The leverage is lower than 2 times from the beginning and finally lower than 0.4, and the possibility of liquidation is also getting lower and lowerr, during which there can be an opportunity to increase the value of the position. But below 2000U is always the same income. This is also one of the disadvantages of the balance strategy.

Let's backtest WAVES again. This currency is quite special. It rose from 6U to 60U at the beginning, and finally fell back to the current 8U. The final profit is 4945, far more than the profit of holding the currency unchanged.

By the way, the performance of the grid strategy is backtested, the grid spacing is 0.01, and the grid value is 10. In the case of nearly 10 times of the increase, both WAVES and TRX have experienced huge drawdowns. Among them, WAVES has withdrawn 5000U, and TRX has also exceeded 3000U. If the initial capital is small, the positions alomst will be liquidated.

## Summary

This time, the backtest analysis used the 5min K-line, the fluctuations in the middle is not completely simulated, so the actual profits should be slightly higher. Overall, the balance strategy bears relatively small risk, not afraid of skyrocketing, and there is no need to adjust the parameters, it is relatively easy to use and suitable for novice users. The grid strategy is very sensitive to the initial price setting and requires some judgment of the market. In the long run, the risk of going short is high. The current round of bear market has been stable at the bottom for some time, many currencies are currently down more than 90% from their highs, if you are optimistic about some currencis, this is a good time to enter the market, you may want to open a balance strategy to buy the bottom, add a little leverage and get profits from volatility and price increase.

The Binance Thousand League Battle will provide free access to the perpetual balance strategy, and everyone is welcome to experience it.
