i understand when using MA with price close we have to use previous candle use , But when closing the position we can use both options (previous candle ) or not use it Right?
Forex Strategy Builder and Forex Strategy Trader sets "Use previous bar value" parameter automatically.
Specifically for closing a position if you wont to close at a MA, you must use the previous bar value. You don't know the final current value of MA until the end of the bar.
If you want to use MA as a closing logic condition, you have to use the current value. The position closes at Bar close price (Time) so the MA is fixed for this bar and you can use it.
if we used the Pivot point as an exit point ( pivot point calculations use the previous bar ) so when enter or exit we donot need to use that option because if we use it it will use the day before previous day Am i right?
Pivot Point plots the points on the same bar but trade according to previous bar points. "Use previous bar" option servers to show that fact to the users.
the charts in FSB draw the actual indicator on chart but use the previous bar in calculations
Yes. That's right.
so to see the indicator at work in MT4 we have to use the shift -1 and it is only found in Moving average but not used in oscillator indicators
You have to apply "Use previous bar value" logic alone in MT. You don't need "Shift". simple use previous indicator value.
if(MACD1 > MACD2 + sigma)
// Enter long
if(MACD1 < MACD2 - sigma)
