Bollinger RVI STOCH and RSI must work together

[hosurtu]

Hi sir; I can say that i read all your forums to find answers of questions but i didn't find my answers.

When I want to SELL;
The candle must touch bollinger bands' upper band
and
in RVI indicator; the main signal must be above of value 0 or main and signal lines must be crosses above of value 0.
and
in STOCH indicator, the main signal must be crosses above of value 75 .
and
in RSI indicator, the lines must be touch value 70 or above of value 70.

When I want to Buy;

The candle must touch bollinger bands' lower band
and
in RVI indicator; the main signal must be below of value 0 or main and signal lines must be crosses below of value 0.
and
in STOCH indicator, the main signal must be crosses below of value 75 .
and
in RSI indicator, the lines must be touch value 30 or below of value 30.

There are some problems in here. For example; stoch always shows buy or sell signal firstly. When stoch main line and signal line crosses, the rvi looks uncrossed happening. so the robot cannot send command. the signal which is came from stoch has been finished while waiting to rvi...
so i want that, stoch must be work firstly, later, the robot must ask to rvi that the main line is above value 70, if it is, third condition: bollinger and last condition is rsi.

i did a thing, but I think the program is not.. i cannot add bollinger bands and rsi. last time, i added rsi but, it did not ever trade..... pls help me. the link: https://fxdreema.com/shared/xgc0TxnIb

Well, under "on Tick" any blocks are doing what they do in the current moment. Conditions are checking things now. Of course, old data can be used, but it is used at the moment. If you know at which candle the crossover must happen, then you can detect it for this candle. Otherwise, of the crossover can be anywhere... well... why not just using > or <, because if line A crosses over line B at some moment or candle, then after this cross line A is > line B for sure.
