# 指标序列
m = 2

# 实时线
close = np.cumsum(series).astype(float)

# 布林线
timeperiod = 5
upper, middle, lower = ta.BBANDS(close, timeperiod=timeperiod, nbdevup=2, nbdevdn=2, matype=0)

# 趋势
qushi1 = np.where(close-middle < 0, 0, 1)# 实时线在均线上、下方
qushi2 = np.where(middle[1:] - middle[:-1] < 0, 0, 1) # 均线上、下行（长度少了1）

# 标签转化为0,1
y = np.where(series==-1, 0, 1)

# 构造特征（注意，已经归一化，全部为非负数）

# 将数据转化为[样本数, 时间步数, 特征数]的形式
X = [features[i:i+time_steps] for i in range(data_len-time_steps-timeperiod)] # [samples, time steps * features]
X = np.reshape(X, (data_len - time_steps-timeperiod, time_steps, -1)) # [samples, time steps, features]

# 标签长度一致

# one-hot编码
y = np.eye(2)[y]

# 划分训练数据、测试数据

# =================================

model.add(LSTM(64, input_shape=(X.shape[1], X.shape[2])))
model.add(Dense(y.shape[1], activation='softmax')) # 输出各类的概率(softmax)
model.compile(loss='categorical_crossentropy',     # 单标签，多分类(categorical_crossentropy)
              optimizer='adam', 
              metrics=['accuracy'])

model.fit(train_X, train_y, epochs=500, batch_size=1, verbose=2)

#检查模型在测试集上的表现是否良好
test_loss, test_acc = model.evaluate(test_X, test_y)
print('test_acc:', test_acc)

效果图

结论

只测试了mod 2的情况，效果不好.

训练数据精度可以达到三分之二左右，测试数据的精度只有四分之一。头脑风暴，几乎可以反其道而行之！可能不失为可行之策。

下一步：

1.画出后20个数据k线图，看是否是震荡区间，亦或是趋势区间

2.换别的指标看看
