In forex, “trading heavy” is a slow-moving market that is struggling to rise, even with buying activity. This often points to a greater likelihood of additional price drops, indicating that sellers are overpowering buyers.
In a market, a downturn is probable, or it could signal that the market has peaked and is on the verge of reversing. It reflects a deficiency in upward movement and a possibility for further price decreases.
High trading volume during a downtrend may indicate panic selling, whereas low volume could imply that the majority of investors, particularly major ones, are not maintaining their positions. In trading terms, heavy denotes that the market or a stock shows frailty and a propensity to decline despite attempts to buy.
