i have a macd/ema strategy with ltc daytrading where i buy on a certain ema on downspikes which should be safe as a support until the corresponding macd goes down. once that macd goes down then the support is no longer valid and i move to the next longer chart to use its ema as support. this works most of the time. however today it just kept going down, and down, and down, without the corresponding macds going down first.
