Need a simple trading robot

Need a robot and strategy which does the following

1. Whenever Heikin ashi candles cross supertrend line upwards [ i.e  HEIKIN ASHI closes above supertrend] in any timeframe, Go LONG IN MARKET ( Not HEIKIN ASHI CANDLE PRICE) and close shorts in MARKET ( Not HEIKIN ASHI CANDLE PRICE)

2. Whenever Heikin ashi candles cross supertrend line downwards[ i.e HEIKIN ASHI closes below supertrend] in any timeframe, GO SHORT IN MARKET ( Not HEINKIN ASHI CANDLE PRICE) and close longs in MARKET. ( Not HEIKIN ASHI CANDLE PRICE)

3. I should be able to backtest this strategy in my chosen timeframe, backtest values shouldn't change / no repainting

4. I should be able to adjust equity on any trade/and set leverage on any trade

5. Once I enter a trade:  a) I should have the option to add position size ( user defined) based on user defined percentage in the money.

      b) Set hard stop/tp for every trade which can overrule the position closing criteria in 1 & 2

6. Position opening criteria should always be as per 1 & 2.
