DEX Limit Orders by Defi Dad

The markets couldn’t be more bullish, and in light of that bullish market structure, I thought it would be timely to share how one can place limit orders to buy or sell using a reliable DEX aggregator. As you’ve probably heard Lark say before, in bull markets, a common pullback after prices surge from local lows to local highs on the daily timeframe includes the 0.236 and 0.382 Fib levels (red and yellow boxes below). I won’t bore you with Fib levels because I don’t claim to be a master of charts. What I mean to call attention to, is no matter what your strategy is for identifying price levels to buy at, one needs to know how to place a limit buy order to “buy at this price or better.”

If you’re new to DeFi but have  traded on centralized exchanges, you might have noticed that you don’t often hear about limit orders in DeFi because automated market makers (AMMs) like Uniswap often cater to a more basic desire to swap. A swap is used interchangeably with market buy or sell orders. So how do we place a limit buy order, using the deep liquidity in AMMs like Uniswap in DeFi, but while guaranteeing the best price at a support level we’ve identified in advance, so we’re not having to rush to our computers and click “swap”?!

One of my favorite DEX aggregators that allows for placing limit orders is the Matcha DEX, powered by the 0x API. While any DEX can use the same 0x API as Matcha, the way Zapper Exchange is powered by 0x API to source the best trading rates
