1。 Don't make contracts with poor liquidity: If one or two arbitrage portfolios have poor liquidity, we should pay attention to whether the arbitrage portfolios can open and close positions smoothly at the same time. If not, you should consider giving up arbitrage opportunities. In addition, if the portfolio is large enough, both contracts of the portfolio have certain impact costs.
2。 Don't do positive arbitrage influenced by non-short-term factors: Because arbitrage opportunities are opportunities to find short-term price deviation based on the long-term price relationship, the factors that lead to arbitrage opportunities are generally short-term or unexpected price changes, so there is generally no need to intervene in positive arbitrage opportunities influenced by non-short-term factors.
3。 The risk of "forced liquidation" arbitrage: its risk is very important in intertemporal arbitrage. Generally speaking, intertemporal virtual arbitrage does not involve spot, but the risk of forced liquidation is that there is no spot position to maintain. When the market situation shows unilateral forced liquidation, the monthly contract with forced liquidation is stronger than other months, and the price difference does not return "rationally", resulting in a loss situation.
