I have this params:

input int     SpreadLimit          = 12;        //SpreadLimit maximum allowed spread in points
// input int     StrategyN            = 3;         //number of case in FcStrategy.MA routine that is the strategy used to determine the buy or sell

input int     ToTimeHourTrade      = 19;        // Hour to stop trade
input int     MaxBarsStillTradeOpen= 10;        // Max number of bars where position can be open, after this the operation is closed
input int     PercOfGainForBE      = 0;         // PercOfGainForBE (0=Disalbed) The percentage of gain for apply Break even

I have a technical specification ready for a custom alert indicator in NinjaTrader 8 (NinjaScript / C#). Important clarification: it is NOT an automatic trading bot, it is solely a visual indicator (arrows/lines on the chart) and sound alerts (notifications) based on EMA crossovers and range breakouts (ORB 15m) on lower timeframes for futures (MES). I already have the exact rules written out unambiguously
A good trend predicting indicator is the one which can identify the trend change as soon as it happens on the chart. when a new candle is formed it should tell whether its going to go up or down. I have already seen a lot of repainting trend predictors so if your indicator is repainting then please don't bother contacting. I would like to see the demo version and then if satisfied , I would want the source code too

1. Use two EMAs: 20 and 50. If EMA 20 is above EMA 50 → uptrend (look for buys) If EMA 20 is below EMA 50 → downtrend (look for sells) 2. Wait for a pullback into the area between the two EMAs. - For buys: price must touch or move between EMA 20 and EMA 50 during the last few candles. - For stils: same idea, but in a downtrend. 3. Entry signal: Buy: a bullish engulfing candle in an uptrend after the pullback
