text: Title: tsignals generating wrong single with more than  2 indicator in strategy
  Body: **Which version are you running? The lastest version is on Github. Pip is for major releases.**
  ```
  panda-ta=0.2.75b
  ```
  
  **Describe the bug**
  tsignals indicator is giving few wrong trade entry/exits in case of using multiple indicators. I've tried to use MACD with two SMA. And results are varying as per the chart.
  
  **To Reproduce**
  ```python
  #dump the attached csv file (it have close column)
  dump_df  #with strategy applied data
  cnd = (dump_df['MACD_13_21_8'] >= dump_df['MACDs_13_21_8']) & (dump_df['close'] >= dump_df['SMA_13']) & (dump_df['close'] >= dump_df['SMA_21'])
  dump_df.ta.tsignals(trend=cnd, append=True)
  ```
  
  **Expected behavior**
  the column generated through np.where in attached sheet have a correct trade. tsignals should match the same value.
  ```
  eg : since it's the AND condition. Thus,final signal (s) should be only valid if all the indicator signal are the same
  s = (s_1 & s3 & s_3)
  ```
  
  **Additional context**
  Note: Problem has experienced in case of more than 2 indicators in strategy. I've generated the actual signals through np. where with below condition and generated column s, which has been generated through s_0,s_1,s_2. column s_0,s_1,s_2 are respectively a signal for each indicator  And it has an expected result.
  
  ```python
  dump_df['signal'] = np.where((dump_df['s_1'].astype(int) == dump_df['s_0'].astype(int)) & (dump_df['s_2'].astype(int) == dump_df['s_1'].astype(int)),test_dump_df['s_2'],0)
  ```
  
  ```
  S* = 0 (No Trade)
  S* = 1 (Buy Trade)  #in tsignal terminology entry
  S* = -1 (Short Trade)  #in tsignal terminology exit
  ```
  
  Thanks in advance !!
