This could be spreaders legging into something, missing the leg and getting out, or it could be an algorithm which wants to take a position but trades both sides to disguise which way it is betting. For example, it alternates buys and sells in different amounts, selling 5000 but buying 6000 for a net position of long 1000, but you won't be able to figure that out in time. It could also be an algo hedging another market, or simply scalping for ticks. It could be a combination of all of these.
You don't know, you'll never know. Don't worry about trying to figure out WHO is trading, just try to figure out what the volume flows mean for your position.
For example, in a sharp drop volumes per bar will often be low, and when you see the market stall on high volume that can be indicative of buying inflow and you should consider either getting out or bringing a stop close to the market. When this happens, markets can reverse and retrace very quickly, you want to be out if that happens, but you're still in if the market drops sharply. |
