The calculation formula of RSI is consistent with the calculation result of the exchange.

MQL5 지표 EA Statistics and mathematics PHP

The calculation formula for RSI indicator is as follows:

RSI = 100 – 100/ (1 + RS)
RS = Average Gain of n days UP  / Average Loss of n days DOWN

Please follow this URL link to learn more about the RSI indicator:


This is my PHP code: $sum_up=0.0;$sum_up_count=0; $sum_down=0.0;$sum_down_count=0; for($i=0;$i0){ $sum_up+=$ch; $sum_up_count++; }else if($ch


The RSI formula you sent out, I know, but the result is wrong. I saw in your tutorial that you have a parameter called RMA. What is the basis of this parameter? our calculation lacks this parameter. Resulting in incorrect results. What is the full name of rma, is it EMA or EWMA.Thank you


Average Gain of n days UP / Average Loss of n days DOWN


What exactly are these two parameters? are they measured by day or by number of candles?


Consult the calculation formula of the index: RSI in the exchange, and ask for consistency with the calculation result of the exchange.
